There is a Cayuga County NY mortgage document record in book “D” at page 536.  Within this mortgage document, Mark Dempsey borrowed money for the purchase of land in Sempronius Lot #16.  The mortgage document is dated March 7th, 1816.  The ‘Mortgagee’ (Lender) is cited within this record as Uriah Carle and the Mortgage description covers all of the 50-acres purchased by Uriah Carle in 1806 via 1806 deed H-157.

NOTE: In 1817, George Duryee purchased the 100-acre parcel of land adjacent and north of land owned by Mark Dempsey in Sempronius Lot #16 via the above cited deed S-307.  Therefore, Mark Dempsey & George Duryee might have been neighbors in 1817. In July 1819, Mark Dempsey’s Surrogate/Probate file shows that George Duryee was one of the two sworn Appraisers that made an inventory and valued  all the personal property within his estate. 

Mortgage records cite that in 1816, Mark Dempsey borrowed money for the purchase of 50-acres of land in Sempronius Lot #16.  He probably purchased this land from Uriah Carle. This deed was never filed with the county clerk’s office.  Later, in November 1818, Mark Dempsey was listed as a 'Mortgagor' in another filed mortgage document for a 29 ½ acre parcel on the east side of the road in Sempronius Lot #17.  If Mark Dempsey purchased the 29 ½ acres from the mortgage lender at the same time he borrowed mortgage money for the purchase…then he may have purchased the 29 ½ acres from Charles S. Cleveland & Robert Lucky in November 1818.  This deed was also never recorded.

After his death in circa 1819, three lots formerly owned by Mark Dempsey (4 ¼-acre, 6-acre, and 29 ½-acre) were presumably inherited and subsequently sold by Joseph & Nancy Gunsaulus. There may have been a remaining 39+ additional acres in Lot #16 that was once owned by Mark Dempsey prior to his death. Note that the description contained within deed HH-41 conveys 6-acres and cites that adjacent land to the north was "IN THE POSESSION OF John Crane". Because deed HH-41 did not say; "OWNED by John Crane"...it is likely that the deed conveying title to John Crane didn't really exist or was not yet recorded in 1825.  Deed NN-508; shows that “John Crane” sold the referenced land located south and west of the 4 1/4 acres conveyed by deed GG-247 in 1830. Therefore, there possibly was a deed conveying land to John Crane from Mark Dempsey that was never recorded.  The deed transferring land to John Crane may have only conveyed 12-acres. The remaining land (that was not sold off from the 50-acres mortgaged by Mark Dempsey in 1816 -about 27-acres), could possibly have been sold to William Wetherby; according to adjacent deed descriptions. 

Consequently, Mark Dempsey may have sold lands to John Crane & William Wetherby prior to his death.  There is no deed filed prior to 1830 showing a conveyance from Mark Dempsey to John Crane. However, John Crane subsequently sold his land in 1830 and he had 12-acres.  If William Wetherby had the remaining 27-acres, via a conveyance from Mark Dempsey, it appears that his deed was also not recorded.
