I have recently found my my Gallivan roots and wondered if anyone could connect with more information. Brothers Cornelius and Jeremiah Gallivan came to Delaware and married sisters there in the 1890's. The surname became Galvin shortly after this. Cornelius marred Albina Collins, and Jeremiah married Norah Collins. The Gallivan brothers were from the Macroom area of Co. Cork. Their parents were Timothy Gallivan and Johanna Leary. They also have one other known sibling, at this time, a sister named Abigail, of her whereabouts unknown. If any has, and would like to share info on this family, let me know.
