Jessica, Unfortunately, I have not been able to find a record of this marriage.Have you tried contacting the San Saba County Clerk?Sometimes they have records that have not been transcribed.You also might try the Lampasas County Clerk, as that is also a possibility.
I must say, this is a fascinating family - filled with infidelity, intrigue, and name changes.
C F and Nancy Matilda are living together in Kerr Co in 1880, and both claim to be divorced - however, I kind of doubt it.
I'm having difficulty with Isabella being born in Iowa.I don't doubt that she was born there, and I know her death cert says Cyrus and Harriet were her parents...but...how do you go from Tennessee(1850) to Texas(1860) via IOWA?????Maybe they took her in when a young child, if her parents died??????
