My Murtha family first shows up around 1851 with my gt. gt.grandfather Lawrence living on Ave. A. He married an Isabella McDonald. He had at least five brothers/cousins who show up around 1855/56 all living on E12th st. They are Joseph who married a Bridget Cullen, Thomas with a wife named Mary,James, Edward and a John. The last three could of been married but its hard puting all the pieces together. Many in the family were printers. Other then my gt.gt. grandfathers family the only otherones I know for sure is the family of Joseph. They were plumbers. I have traced them to 1900. Joseph had three sons, Joseph, John and William. The son William married a Mary Ellen Anderson and also had a Joseph for a son. This is where I stand now. Looking for some help[.
