Some of your McElroys wouldn't have connections with Johnson, Meadows, Wallker's ,would they? I'm not sure if I have a given name for my Mc. or not. He was called Mack of course and I have found him with initals M. C. and M. L. He was born ca. 1850 in Ga. married Martha E. Johnson b. 1861 Ala. They were in Tex in the 1900 census. Had a daughter named Ziposa and other children . was enumerated with John Walker in the census as nephew. He went back to Ga. after Martha died in 1927 to be near his first family and died there in 1930 or early 1930's. Thats all the information I have on him other than he was a Baptist traveling preacher.licensed in 1918.
