Nan Tinker--Sarah Ann Swagerty--was my great-grandmother.
She met her husband George Edward Tinker while working as a hired girl in his half-sister's house.
One of my cousins has set up an expanded Tinker family tree on Ancestry.com. It's "public".

Also, Lou Burns, Turn of the Wheel: A Genealogy of the Burns and Tinker families (1980; out of print but in some libraries), has a lot of info on many branches of the Tinker family in Oklahoma.
