Thank you for your informative reply. The fact that our Arnall ancestors might have changed their names to "Arnold" from time to time is intriguing, especially since I have links to both Arnolds and Arnalls in Coweta County, Georgia.
John Gholston Arnall was buried in Oak Hill Cemetery in Newnan, Georgia. When I find the picture of his gravestone (I need to index these things.), I will send it to you in an email. Many Arnalls are buried in Oak Hill, including Governor Arnall. Governor Arnall was a part of the infamous three-governor controversy in Georgia a few decades ago. He was Georgia's youngest Governor. There are several renown stories about this storied Governor if you are interested.
'My line from William H. is:
1) William H.Arnall
2) John Gholston Arnall
3) Elizabeth Gibbs Arnall b. 6-27-1825 d. 10-29-92
4) Millard Courtney Farmer b. 4-1859 d. 1911
5) My paternal grandmother Sarah Farmer b. 4-15-1897 d. 1-5-1984
Millard Courtney Farmer's wife was Mollie Arnold, my great grandmother. Hence the cross in the Arnall/Arnold lines in Coweta County. The "Gholston" name reappears as a middle name in the Farmer line.
Thank you again for the info, cousin.
