Vivian, There are not any Fannin marriages (including the variant spellings) listed.
Ironically, I am also researching the Fannin family. I have had a heck of a time finding information. I am descended from Joseph & Nancy Fannin. Joseph Fannin was born about 1869 in Illinois. Their son, Thomas Fannin, married Priscilla Ussery. Joseph & Nancy also had a son named Joseph.
There seems to be some ties to Chicago.
I would love to compare notes with you. I could use any help I can get with my Fannin line.
