Maureen, please email me if you read this
We are looking at the same relatives, but I didn't have any of the information you provided in your blog here.
Peter John Galvin born April 24,1854 Preston,Lancashire England - his family had fled the famine. Peter John Galvin came to Massachussetts June 1871. He met and married Maria Gallagher July 12, 1872 at St. Josephs Church.
I have a typed narrative "pedigree" that Peter John Galvin wrote with copies of baptismal certificates for his son, John Galvin born April 18, 1873, daughter Winifred Galvin born July 12, 1885, and Agnes Galvin born November 13, 1880.
I just found a census listing the two other sons, Luke (Lucifer), and Patrick Thomas. Peter John Galvin's son Patrick Thomas is known as Thomas Patrick married to Martha Jane Hogan, son Thomas Alfred Galvin, moving to NY around 1913.913.
Please write back so we can put our research together.
Sincerely, Martha Galvin
