Where did you get this information?
"In 1910 Michael & Mary E,'s eldest child, John, was 8 years old and born in Penna. so they were living there by c1902." This I am guessing you the Census, John was actually born Aug 9th, 1901 (birth record).
"Married 14 years so c1896 with 7 children (only 3 living)." - No Idea where you go this. I didn't know when they were married or that they had 4 children who died. The 3 living children in 1910 where John Joseph (1901), Helena (1906) & Edward (1909). They had 1 other surviving child, Thomas (my grandfather) born in 1911.
" Michael to U.S. 1890. By 1920 the family are living in Philadelphia (that from the Census) & Michael gives year of arrival in U.S. as 1886 as well as year of naturalization as 1896" - I have both years a possible arrival dates and the naturalization date as well from ancestry.com. I have been trying to tie either of those to ship registries.
Michael died at the age of 77 in 1948 in Philadelphia Pa. I have an archives looking for his obituary. Didn't think of going to the state for a death record. I will look into this.
Michael's birth year we know was c1871 do to census records. Being born in Wexford with a father's name of Andrew is information that I got from my father's cousin (they both had Michael as a grandfather) who apparently did some research when he was in Ireland. Unfortunately all he has was printed documentation which he misplaced and has been trying to find for a few months now with no luck.
My aunt remember Michael being very proud of being a Footman before coming to the states.
I believe this is about everything that I have on him. If I thing of more or find anything else out, I will post it.
