A Book describing Alexander's early life. As quoted from a fellow Beall researcher "It really makes you feel like you are acquainted with him. I see that familysearch.org has it but I couldn't get into the book from home today.. . Perhaps it's just my computer? I'll have to check it out later:
"Alexander Beall - 1649-1744 of Maryland: One line of Decent in America" compiled by William Hunter McLean. I also see you can order the book through the Fort Worth Genealogical Society.
