Ollie, The first clue is that most of her ALSOP siblings in this family moved to either DC or Maryland. The second clue was there were no Farmers in 1900, 1910, or 1920 in Spots.

The image for William's occupation seems to say "Hostler" Also, it is odd that Mary stated 10/2 children, as there were 8 children that were enumerated. (Could this have been a second marriage for her?) Based on the facts that were in the Census, this looks like the family you are seeking.
