I know there are manby Horrigans in the Boston area. I see many of them on Facebook. I am trying to find the link that comes to America. Working backwards I have some names but cannot find the link coming across the pond. My father started the search but was stonewalled at the same place. Guess I'll have to look at death certs of mt grabdfather in Baltimore, MD to see what was entered for his birth place and go from there. Daniel Horrigan was born in Ireland around 1817 and Married Ellen b1822 died 1889. This is a full time job for sure!!
