I know that Stallard is a popular name in Kentucky and Virginia.
This may or may not be of help to you.My grandfather, William Stallard, was born in Kentucky in either 1914 or 1915.
My Stallard roots are quite blurry since most of my family has since passed on.Anyways, my William Stallard died in 1979 in Chicago, Illinois.His wife's name was Ruth Stallard.He had two children, Maryann & Daniel (my father).I am his only grandchild (Jenine).I know my grandfather had some brothers but the only one I remember was my great uncle John.
I haven't been in contact with many Stallards in Kentucky but I know that most of them are settled around Louisville. I know that there are also a number of Stallard folks in Arizona as well.
As far as I know, my branch of Stallards have been in this country for ages and ages.I remember being told that there was a book written about Stallards & their history that was researched by someone I am related to but I was very young and I don't know what direction to send you (I would be interested in it myself).
If any of this sounds familiar to you or I can be of any help, please reply to this post.
