Lucy appears to be the sister of Rev. Charles Stewart, Aaron Stewart who went to Winston Co. MS., Hazael Stewart, who went to Kempert MS. and Hugh Stewart. A son of Aaron Stewart states in a bio "A History of California and an Extended History of Southern Doast Counties" Vol II, pub 1907, digitalized by Google (online, original page no. 1708), that their father was Thomas Stewart from Scotland and NC. Lucy is living near Hazael in 1840 and 1850 in Kemper MS. Hope this helps.
