My McGarrity family came to Harrison, New Jersey, and, apparently, Philadelphia.
Three siblings: Catherine McGarrity (my great grandmother)died 1951 m1 Thomas Nelis m2 William L Donnelly (my great grandfather)
Margaret McGarrity, much younger sister, never married, died 1932
Margaret came to the US much later, in 1912, apparently after the death of her parents. She arrived through Ellis Island, so I have much better detail of where she had lived and where she was coming. Her arrival record shows that she will be met by her sister Mrs Catherine Donnelly, with full address in Harrison, New Jersey.
It also appears that Margaret came to the US twice - the first time in 1900, to be met by an unnamed brother, in Philadelphia. The arrival record does give his address, and I believe that I have confirmed that his first name is Michael.
I'm trying to piece together the names of their parents and possible other siblings. I've found a family in Carrickmore which appears to fit, but I am still looking for confirmation. Possible additional siblings: John, Sarah, Patrick and James.
If any of this sounds familiar, would love to exchange information. Although my great-grandparents had at least 9 children, our family has dwindled in recent generations, so there seems to be no on else to research our past.
