Peter Hanley b. 1862 in ireland to NYC 1903

I am looking for a Peter Hanley born in Ireland in 1862.Came to NY in early 1900's(1903?).He came to NY with his wife and 4 children, Mary(b.1897), Thomas(b.1899), Peter Jr.(b.1900), my g-gma Irene(b.1901) and had his final child Gertrude in 1904. According to the 1910 census he is listed as a widow, possible complications during the birth. After the children grow I can find no more info on the family
