Good afternoon, Angela.
I don’t know for sure the names of Robert Benjamin Welch’s parents, but I think they are to be identified as William Welsh (note the variant spelling) in the 1870 Federal Census of Crenshaw County, Alabama, and his wife Delila:
Township 10, Rutledge, Crenshaw County, Alabama
29 June 1870
Dwelling 171/Family 171
Welsh, William, age 62, farming, real estate $400.00,personal property $500.00, born in Georgia.
Delila, age 52, born in South Carolina
John, 18, Alabama
George, 16, Alabama
Jackson, 14, Alabama
Jefferson, 12, Alabama
Benjamin, 10, Alabama (He would have been born about 1860.)
- - - - -
I wonder whether William had another family before this.In the 1850 Federal Census of Pike County, Alabama, I find the following:
[No Township or town named], Pike County, Alabama
20 September 1850
Dwelling 100/Family 100
Welch, William, age 40, Farmer, born in Georgia
Sarah, age. 38, born in Alabama
Nancy, 18, Alabama
John, 13, Alabama
Seaborn, 9, Alabama (A Seaborn Welch married Matilda Everage in 1868 in Crenshaw County, and I wonder if this is he.)
Easathan (?)(male), 7, Alabama
Mary, 6, Alabama
George Ann, 3, Alabama
Samuel, under 1, Alabama
The 1850 and 1870 Williams are both born in Georgia, are about the same age, and may live in the same area – remember, the western part of Pike was taken to form part of Crenshaw County in 1867.The children of the 1850 marriage would by 1870 have established their own households.If Delila died about 1851, William Welch might have married Sarah soon thereafter and begun his second family.
This is speculation, of course, and there may be nothing to it.
