The plaintiffs have filed their bill in equity asking this court to restrain the defendant from further prosecuting two actions in the superior court against the plaintiffs severally, as occupants of distinct parcels of land, to foreclose a mortgage made by Joel Kilborn to Charles N. Emerson, bearing date June 5, 1849, to secure the payment of a note of $313, which mortgage, and note were assigned by Emerson to the defendant on the 30th of November 1850. They allege in their bill that nothing is due upon said mortgage, or, if anything is due thereupon, that they should be charged with only a part thereof, alleging that the defendant is the owner of certain other premises that should be charged pro rata with payment of such sum. They also claim to be the lawful owners of certain prior mortgages, one made by Robert Kilborn to Jeremiah Atwood, and another made by said Joel Kilborn to Robert Kilborn. They also in their amended bill offer to pay whatever sums, if any, the court shall find to be justly due to the defendant as assignee of the said Emerson mortgage, which is properly chargeable on the lands they occupy.

The first inquiry is, whether the allegation of the plaintiffs as *470to payment of the sum secured by the mortgage to Emerson has been sustained by the proof. Upon this point the plaintiffs have, in the opinion of the court, failed to maintain then allegatian. Nor are any such facts shown as are requisite to sustain the defence of an equitable estoppel against the defendant’s enforcement of his mortgage.

Assuming this to be so, the plaintiffs then insist that the entire premises described in the mortgage of Joel Kilborn to Emerson should be charged with the payment of the debt secured by that mortgage. Upon this point, it appears that the mortgage included not only the premises demanded of the plaintiffs in the 'suits against them, but also another parcel of land called the Leavenworth Grove lot. But this lot, after having been thus mortgaged to Emerson, was sold and conveyed by deed of warranty by the mortgagor to the defendant. The effect of this sale by the mortgagor of a portion of the mortgaged premises was to exempt the land thus sold from any contribution towards payment of the mortgage, as against Joel Kilborn, the mortgagor, and those claiming by subsequent conveyances from him. Such subsequent grantees would acquire no greater rights than the grantor had. As between the defendant and Joel Kilborn, and the subsequent grantee of Kilborn, the Emerson mortgage was after this sale chargeable on the fifty-four acre lot, and the owner thereof had no right to recur to the Leavenworth Grove lot for contribution. Bradley v. George, 2 Allen, 392. George v. Kent, 7 Allen, 16. Welch v. Beers, ante, 151.

The subsequent purchase of the Emerson mortgage by the defendant did not affect his right to have the Leavenworth Grove lot relieved from contribution towards the payment of it, such discharge from contribution having been fully effected at the moment of the conveyance with warranty by Joel Kilborn, the mortgagor.

No difficulty arises in the present case as to the Atwood mortgage, which was of a prior date to the Emerson mortgage. That mortgage is wholly discharged. It was paid by Russell Kilborn, who had taken a quitclaim deed of certain lands from *471Robert Kilborn, the mortgagor, bearing date April 22,1851, in which it was stipulated that the debt secured by this mortgage should be paid by said Russell Kilborn. The cases of Wedge v. Moore, 6 Cush. 8, Bolton v. Ballard, 13 Mass. 227, and Brown v. Lapham, 3 Cush. 551, seem to be decisive in requiring us to hold this to be a payment. The principle stated in these cases is to the effect that where the money is paid by one who has assumed the duty of paying the debts, by contract with the mortgagor, or those succeeding to his rights, this must be taken, as regards other subsequent interests, as a payment; and this must certainly be true when the party takes no assignment, but contents himself with a naked acknowledgment of payment and discharge of the mortgage indorsed thereon.

The defendant’s rights are in no way affected by the mortgage of Joel Kilborn to Rossiter, that mortgage having been made subsequently to the Emerson mortgage, and also to the. conveyance by Joel Kilborn to the defendant.

Nor do we see any ground for the position taken by the plaintiffs that it should be required by this court that the Emerson mortgage should be satisfied wholly out of the Leavenworth Grove lot, because the subsequent mortgage to Rossiter only embraced the other land. The mortgage to Rossiter was made subsequently to the time when the Leavenworth Grove lot was exempted from contribution by the sale with warranty to the defendant. On account of this subsequent title, those who hold interests under that mortgage cannot set up any claim in reference to the Leavenworth Grove lot, or subject it to contribution, either directly or indirectly; much less charge the entire payment of the Emerson mortgage upon it, to the prejudice of the purchaser of the same from Joel Kilborn before the Rossiter mortgage existed.

The claim of the plaintiffs, that they have succeeded to the interest of Robert Kilborn, as mortgagee of the interest of Joel Kilborn, presents a question of more difficulty. This mortgage was dated March 13, 1849, and is therefore earlier in time than the Emerson mortgage, and covers the fifty-four acres demanded by the defendant in his actions pending in the superior court. *472On the 22d of April 1851, said Robert, in consideration of one dollar, remised, released and forever quitclaimed unto said Russell, his heirs and assigns forever, “ all my right, title and interest in and to the following real estate, all and singular the same premises conveyed to me by the said Russell by his mortgage deed to me, dated March 13,1849.” “ Also all and singular the same premises described in a certain mortgage deed given me by Joel Kilborn, dated March 13, 1849.”

The cases of Hunt v. Hunt, 14 Pick. 374, and Barker v. Parker, 4 Pick. 505, seem to support the position that this conveyance by Robert Kilborn to Russell Kilborn would pass the interest of Robert Kilborn as mortgagee in the mortgage made to him by Joel Kilborn. This would certainly be so, unless the surrounding facts, and the circumstances connected with the conveyance to Russell, should make it appear that this mortgage was to be treated as cancelled.

But assuming that this conveyance to Russell Kilborn was sufficient to pass to him the mortgage in question, then Russell Kilborn would be the owner of a mortgage prior in date to the Emerson mortgage. If he did thus become the holder of this mortgage, his rights as such assignee of the mortgage would not be defeated by his having become the owner of the equity of redemption of the premises. There has been no evidence introduced to show any breach of the condition of this mortgage. The case is barren of all evidence upon this point. If such prior mortgage exists, and there has been any breach of the condition, the defendant, as second mortgagee, can acquire the actual possession of the premises only by redeeming the same and paying such sum as may be justly due thereon. But the existence of such prior mortgage does not operate to defeat the actions by the defendant to foreclose his mortgage, Russell Kilborn holding the equity of redemption of the second mortgage, as well as the alleged title of assignee of the first mortgage, Cronin v. Hazletine, 3 Allen, 324. The judgment for the defendant as such mortgagee would be a qualified one, as to disturbing the possession of any one having a prior mortgage, but valid and effectual to foreclose the second mortgage as against *473all titles subsequent to it. We do not perceive any necessity for maintaining this bill for the protection of the interest of Russell Kilborn, as assignee of the mortgage to Robert Kilborn.

The suits instituted by the defendant to foreclose his mortgage having been first instituted, this court will not sustain this bill and stay the proceedings in those suits, although the plaintiffs in their amended bill offer to pay all such sums as may be chargeable upon the lands held by them. The amount justly due upon the Emerson mortgage may be settled in those suits, and the payment of that sum will relieve the premises from all further charges thereon by reason of such mortgage.

Bill dismissed.
