Armistead Virginia Area

Hi!
I am tracing the Armistead family from my husbands mother's father and was wondering if anyone can help me out. Here's what I have:

Howard Armistead-1930 Virginia to 1990 married Barbara Millard
Roy Fenton Armistead-1909 Virgina to 1996 married Nannie Condrey
Alaska Columbus Armistead-1883 Virginia married Deborah
Thomas Armistead-1857 Virginia married Fannie

Any help would be appreciated

Thanks
