Hello,

Here is what I found. Your George Wilder married Isabella Smith July 24, 1875 in Dougherty County Georgia. They were listen in the 1880 census, here is how it was listed.

Wilder, George- head- male- mulatto- age 45
------, Isabella- wife- female-mulatto age 30
------, Mary- daughter- female- mulatto- age 9

1900 census- Georgia, Fulton County- Atanta Twp

Wilder, George, head- male -black - age 60
------- Isabella- wife- female- black- age 40

As far as I could find they had only one daughter

Hope this help
