Brandi, I can't find the Hiram Bedwell profile. Is it posted in your family tree. Names of wife, son's, DOB, DOD, places they were born & died?
I have Bedwells in my family & have hit a brick wall for some of the same reasons you are having. Numerous marriages, similar named wives & children, brothers, sisters & parents. Tennessee is tough because so many records were destroyed either by fire or the war.
Try the census, wills, grave info. You can message me & we can work together. Maybe we will find we are related?
