She was born in December of 1859 and died 1929-07-03 in Dekalb Co TN. She married Andrew P Rigsby on 1878-07-14. They had 7 children that I know of: Osa, Haskel, Henry B, Wade W, Mattie B, Harrison, and Era or Eva M.
Her mother's name was Mary, but I don't know her father's name. Caladonia appears on the 1860 census in Dekalb Co on page 194, Sligo Post Office:
Mary Dildine 37 TN George W 17 TN Rachel 13 TN Aaron 12 TN Caladonia 1 TN
That 11-year gap looks suspicious to me.
I have not searched thoroughly, but a cursory glance at the 1850 census shows no Dildines in Dekalb Co TN.
I have more on Andrew Rigsby if you're interested.
