Mary was the daughter of Christopher Reed. She and her husband came to Butler County either with Christopher or soon thereafter.

We know Abraham as David’s son because his brother George named him in his will. Abraham pre-deceased George, the will referred to Abraham’s heirs.

No baptism was recorded at Longswamp for Abraham. Some went unrecorded so it may be his was one of them or perhaps he was born after the family moved to Northumberland County. His age bracket in Census places his birth sometime in the 1780’s. 1785 is just a ballpark estimate.

I know the birth dates of David’s other sons, so Abraham is placed as his third son only based on my ballpark estimate of his 1785 birth. He is designated P2c.

Allen Tallman wrote this about Abraham. "Abraham Martz married in 1808 Mary J Reed, daughter of Christopher Reed. Soon after Abraham and Mary married they removed to Butler County, Ohio. Some say Abraham moved with his father-in-law but Christopher purchased his land in 1807 which would indicate Christopher Reed may have moved earlier. Abraham and Mary later lived on this land and worked it while the country was wild and undeveloped. His father-in-law gave him a free hand on this land and Abraham soon owned it. Upon this place is an old stone house built in 1815 by either Christopher or Abraham. When built, it was considered quite an elegant residence, and was among the best buildings of that day.”

I don’t know where Abraham was living in 1810, perhaps already in Ohio but the 1810 Census for most of Ohio was lost. Abraham was listed in Madison Township, Butler County in 1820-1840 and then his widow Mary was living there with her married daughter in 1850.

Allen Tallman says Abraham died in 1848. I can’t independently confirm that but it was obviously sometime between the 1840 and 1850 Census based on his presence in the former and absence in the latter.

Abraham is not, as of summer 2015, on find-a-grave.
