Thelma, I can give you a little on Lawson J. Sipes, although some of it conflicts with your info. He was born May 23, 1833 in Harrison Co., IN and died March 30, 1916 in Loma Linda, San Bernardino Co. CA. He married Lucinda Wright November 17, 1857 in Bladensburg, Wapello Co.,IA. She was born March l30, 1842 in Bladensburg and died Dec. 16 1916 in Carthage, Jasper Co., MO.
Lawson was son of David E. Sipes (1797-1852) and Mary Jane Jones. The names of his children and siblings corresponds with my info. I could give you more information if it would help. Could the date on Lawson's letter be earlier than 1940?
I'm sorry I do not have the SAVERY name in my database. What was Savery's wife's maiden name? I would very much like to have a copy of the letter.
