Notes:

He purchased the west one half of Section 14 in Township 5, Range 5 of Randolph Township, Montgomery Co., Ohio (C-2537) Jacob was taxed for his property in Randolph Twp. in 1809. (C-1025) He also apparently had land that he owned in Ashe Co., NC at the time of his death.

In his will, it was stated that his nephew, David Mast, of the state of North Carolina, should sell Jacob's property of said county of Ashe, dated Oct. 4, 1809. (C-422h) Though children weren't listed in his administration, it appears that his two oldest daughters, heirs of Jacob Mast, Sarah age 12, and Rebecca Mast, age 10 asked their Uncle Leonard Eller to be their guardian in an 1815 Montgomery Co, OH court record. His youngest 2 daughters were Nancy (b. 1809) and Sussanna (b. 1807) (C-2172, 2320, 2537)

This Jacob seems to be confused with another one, supposedly from the same ancestry according to Beers, History of Champain Co., OH, c. 1881 (p. 819) "John Mast, retired farmer; .P.O. Urbana, born in Pennsylvania Oct. 29, 1793; is a son of Jacob and Barbara (Kenaga) Mast, natives of Pennsylvania. The maternal grandfather was a native of Switzerland, coming to America when about ten years of age. He lived and died in Pennsylvania. Jacob and Barbara also lived and died in Pennsylvania, and were the parents of seven children; three now survive -- John, Isaac and Leah. These two cannot be the same Jacob who is the son of John Mast --- but possibly could be the son of his brother Jacob Mast who would fit a similar description. (E)
