Hello all! I am researching Marshall & Lindsay in this area of Pa.I am pretty sure John & Margaret Marshall hail from Wilkinsburg in the late 1700's, but they had a daughter Margaret (b.2-2-1828 d. 5-9-1890) who married William Lindsay (d. 2-2-1886) and he was "from the area". Any help would be extremely useful in storming this brick wall. Tony
