I have info on all of Wm.H's children except Mary.
I've worked on the Hitchcock line alittle in Md.I have nothing on the Harrington line except they are probably from Ireland.Margaret Cobb Tacker's father was James Cobb.
A friend in Corinth Mississippi gave me a copy of his work on the Tacker line.He said he would donate all his work to the library in Hardin Co. TnHis name was Ralph Seay, his mother was a Tacker. I'm hoping his work was received.
What state do you live in?There are few men with the Tacker surname.There are only 4 men in our from my grandfather to carry on our name.
