I am looking for information on my greatx3 grandparents.Robert Allen (b. 1850) and Bridget (b. 1845, maiden name unknowm) are both originally from Ireland according to the 1880 NJ census.They had at least three daughters: Catherine (b. 1869, NJ), Ellen (b. 1873, NJ) and Elizabeth (b. 1871, NJ - also called Eliza).
I would like to learn more about their Irish origins, Bridget's maiden name, and the rest of the Allen descendants in Passaic, NJ.
