Connecting Parker as a child of Christian & Sarah Grim is based on Dorothy Hennen’s research, and analysis of census records.

1850 Census, Aleppo Twp., Greene Co., PA478
88/88 Grim, Parker, 35, b. PA
Catherine, 36, b. PA
John, 2, b. PA

1860 Census, Aleppo Twp., Greene Co., PA756
322/322 Grim, Parker C., 44, b. PA, Personal Estate $250
Catherine, 45
John, 12
George, 10
Demas, 7
Elias, 4
Note: This is next door to Parker’s brothers, Jacob & Lebbeus (Lebbeus was living in Jacob’s household). This, along with age of children in the 1840 census for Parker’s father is what convinced me that Dorothy Hennen was correct; that Parker, is indeed the son of Christian & Sarah Grim.

In 1861 Parker sold land called “Magazine” to Christian Grim in Aleppo Twp., Greene Co., PA.
