I am still working on that part of my family. My gggrandmother was Ida Maxwell. Sevier County Arkansas. I was told that she ended up in Oklahoma. Her father was Alexander. There is an Ida Maxwell listed on the National Archive site at NARA.com along with other Maxwell's.
Ida Maxwell married a Bill(William)Stanford.
Alexander Maxwell's father was Henry Maxwell.
You can e-mail me at jnewnum@sprynet.com and I will try to help you. I know that married into that Maxwell group were Cowan, and Skinner.
