I have found three branches of my Carroll family:
1. Newburgh, Orange County, NY
Patrick Carroll/McCarroll (b. abt 1810, Co. Tyrone; d. late 1850s, Newburgh, NY) immigrated to U.S. abt 1851 married to Susan Gough/McGough. Five children: James G., Bernard, Edward, Mary and Abram all born between 1840 and 1858. Family name in Ireland may have been McCarroll.
2. Carroll's in Camden, NJ around 1890 through 1908 including John M. Carroll, John and Catherine Carroll and James T. Carroll (son of James G. listed above). Somehow John M is related to Patrick -- maybe nephew.
Ran a family rug company with Fries, Mullens, Breslin and Murphy. John M. Carroll lived in Philadelphia in early 1890s.
3. James G. (listed above as son to Patrick) moved to Brooklyn around 1870 and had the following children from two marriages: James T., William, John, Howard and Maybelle (all born from 1875 through 1900). James G. born in Co. Tyrone abt 1842 died in Brooklyn NY in 1911.
