Jacob Henderson was an Irish clergyman and philologist who emigrated to the colonial Provinces of Pennsylvania, then Maryland, where he became a prominent land owner and church leader.
[2][3][4] Duvall had purchased sizeable tracts of land, including Catton, later known as Belair as well as owning Middle Plantation in Davidsonville, Maryland.
[9] Mary had previously inherited Middle Plantation in Davidsonville, Maryland when her first husband, Mareen Duvall died in 1694.
[1] In 1713, St. Anne's Parish in Annapolis, Maryland had become vacant and Henderson was asked to serve there as well, despite living about 20 miles (32 km) away.
[3] In 1723, the Bishop of London, Dr. John Robinson died, and his successor, Dr. Edmund Gibson chose not to renew Henderson's appointment to the Mission.
[1] In 1737, Henderson gave the chapel and 4 acres (16,000 m2) of land for the use of Queen Anne's Parish called "the Glebe whereon there is a Chapple now standing."
[1] On 30 March 1737, for the sum of £500, Henderson sold three parcels of land to Ogle for him to build his Governor's estate.
[5] On 6 July 1737, Ogle granted Henderson leave of absence from the Province for 18 months to return to England.
After specific bequests to family members and friends, he bequeathed the residue to the Society for the Propagation of the Gospel.
[13] His wife Mary (née Stanton) wrote her will on 2 October 1761 and was probated on 18 February 1762 in Prince George's County, Maryland.
