Please go to mcdade.bravepages.com and post this same query on the Forum page and place your little icon with your direct line included in your comments on the US map page. I think you are probably in the same line as our webmistress. Mary is from an AL line, is quite familiar with that line,and has a lot of McDADE's in her database. You are probably about a sixth cousin to my husband, but most likely several generations more closely related to Mary. Each of us who is active contributes the part that we know and the links begin to fall in place thru our cooperation.
The AL line that I am aware of came out of MD/VA > NC > GA > AL then > LA > AR & TX and, of course, many other places by now.
Good Luck, Cousin, and enjoy our working together to help everybody at mcdade.bravepages.com
