Lavelle - Peter, Mary, Ellen, Bridget

Hi All,

I am searching for information on my great grandmother, Bridget Lavelle (8-18-1885 to 12-23-1950). She and her siblings, Peter (6-26-1878 - 4-16-1957), Ellen (6-18-1882 - 1-16-1975), and Mary (9-29-1880 -  7-24-1973) immigrated to Pittsburgh, Pennsylvania, USA around 1900-01 from Galway and they may have come separately.  Census data varies with immigration dates but Mary was married in Pittsburgh by 1902 to Patrick Mullen and my grandfather was born to Bridget in Feb 1906 in Pittsburgh.  Peter remained single. Ellen married William Barker. Bridget married James Holleran, my great grandfather, and later James Gauden. Bridget had one son, my grandfather , James, then with her second husband a daughter and son, Virginia and Albert. Elllen and Marynhad several children and I have that list. 

According to Peter's death certificate, his parents were Patrick Lavelle and Julia Feeney. 

 It is presumed that there were more siblings who did not come over, namely, Kathleen, William, John, Patrick, and Fay. 

According to Ancestry DNA, my Dad fits into their Connacht Ireland area, then narrows to North and South Galway. The matches I have there show one known grandchild of Ellen, and then some unknown people with the Feeney name, amongst others (299 matches in that area). 

What I am really looking for is some/any Ireland documentation of the family and to pinpoint where they lived. I may have found a ship manifest with Mary from Clifden arriving in 1901 and going to a cousin's ( B. Vaughn) with the cousin's sister, Annie,  in Castle Shannon (area of Pittsburgh, where I happen to live now and just a few miles from where they all settled in the West End of Pgh) but I am not sure it is her since I have no knowledge of the Vaughn family.

Any connections or help is welcome.  My email is jenster11174@yahoo.com.
