One of my great grandmothers is Margaret Louisa Farnsworth; her first husband, Albert Washington Highfill, is one of my great grandfathers.They had a sizeable family, several of whom died before they reached adulthood. Their children included, among others, Albin B. Highfill, William Edna Highfill (one of my grandfathers), Oscar Highfill, and twins, Roy and Loy Highfill.Roy died in childhood.
One of my grandmothers, Barbara Ellen Millard (married to William Edna Highfill) James William "Jim" Millard married a second time to Prussia Farnsworth, after his first wife died. They had a couple of children, one of whom was Oresta Cheedle Millard.He was about the age of my father, William Herman Highfill, who died a couple of years ago.He would be 90 now, had he lived.He could probably have answered your question off the top of his head, but that option is not available, of course.
I have been told that the Farnsworths came to Scott County, Arkansas, in the 1870's, I believe, from Walker County, Georgia, via a wagon train.Perhaps the Scott and Yell County censuses could help answer your query.Given the fact that Scott County, Arkansas, and LeFlore County, Oklahoma, are contiguous, I would guess that your Farnsworths are related to the Scott County Farnsworths.I do know that some of the Farnsworths lived in Waldron, Arkansas, and Heavener, Oklahoma, is the next town west of there that is of any size at all.
