Harris Sanders Murdock was my Great-Grandfather. Mary Elizabeth (Mollie) Dotson (b. 20 Feb, 1862d. 1 Apr 1943) was his second wife (and my Great Grandmother). Mollie was a fairly common nickname for Mary, & I have several Marys in my family tree who were called Mollie. Her father was Jeremiah (Jerry) M. Dotson & he was a Sgt in Company G 18th Texas Infantry CSA. My Grandfather was Martin Sanders Murdock - and I am still trying to figure the source of the "Sanders". I met several of the "old" Murdocks at a family reunion about 1947, but I don't recall their names - I was about 6 years old at the time.
If you haven't seen it, you might be interested in seeing the Murdock cemetery. Just go to the url below, then scroll down to "Murdock" & click on it. the site lists all the people buried there & each name is a clickable link to a picture of the stone. H.S. & Mary are both there, but Caution - it may be a pretty slow load.
