Hi: I checked the birth record of Margaret Ann McCann born in Mass on Jan 1,1853, I find that her Parents,(My Great Grand Parents) Peter and Margaret McCann were from Londonderry, Ireland. Still searching for the other children born in Ireland : Thomas, Patrick; Michael and Ann; Thomas came to the USA in April 1852, He was born in 1840,so would have been only 12 yrs old. Searching for Ship that left Liverpool , Docked N.Y. Ann Meyer(Ann McCann)
