I have just discovered my great grandmother Mary Davidson Walz , was a granddaughter of Rev. Andrew Baker Davidson. She died in Davenport, Iowa, when her only child, my grandfather, was 2 or 3, so this Davidson family history was lost. Her husband was also originally from Lexington, Va., where they presumably married; his German immigrant father (William Walz) fought for the CSA in the Stonewall Jackson Brigade. Any info you have on William and Martha Davidson and their ancestors would be greatly appreciated!! Thank you in advance!
