Regarding your inquiry into the parents of Francis Munday, I too am searching for this information. My wife's mother was a Mundie from Baltimore and have so far traced her Mundie (Munday) heritage back to Robert Munday b. 1806, Occupacia, Essex, Va. In a death notice listed under Robert Mundie d. Feb 1889, he listed his parents as Frances and Elizabeth. Did not know of any other siblings until I saw your info. Did find Francis Munday in a 1830 census along with several other Munday's on the same page - Benejamin H., Edmund, Meridith, Johnson, Thomas, Mary, Louis, James, Louis Jr. and Mirajah? Since the 1830 didn't give names in the household but just a count in age ranges it looked like Elizabeth was listed (same age range as Francis). In the following 1840 census Elizabeth was listed as 'Head of Household' suggesting Francis had died in between. I have a hunch that Benejamin H. Munday is tied in some way since in his will he mentions 2 grandsons named Robert. It was written in 1840+ after Francis would have died. No confirmation on much of the latter yet.
Any info you have would be very helpful. Thanks, Ed
