Hello, Would anyone be able to look up this Mattingley for me in the 1840 Washington, DC census? This person is listed on page 176 according to Ancestry but there is no copy of the census. Still looking for my John Mattingly whose parents were Ann Carbery and John Mattingly, both originally of St. Mary's Co, MD but moved to DC. John Mattingly may have attended Georgetown U in 1825 but probably did not graduate. John's son, Thomas Joseph Mattingly, was born in Moorefield, VA in 1827 and moved to DC around 1832. John was deceased prior to his mother's death in 1855 and his wife, unknown, was also deceased by then. This is certainly my BIG brickwall! Thanks in advance for any help. Best regards, Elizabeth Culhane Fairport, New York
