I am trying to locate my great grandmother Margaret Cahill who I believe immigrated in 1887. She was born in Tipperary, Ireland Dec. 14 1869 and came over when she was 17 as per her obituary I found. I am having trouble locating her on any ships lists. I don't know if she came by herself and if there was anyone in the U.S. when she got here. The obituary states she lived in Troy, NY the rest of her life which means she probably came into New York but Troy, NY is in upstate NY and Boston isn't that far either. Not been able to pin her down. Anyone who could help me with this? Even though she would turn 17 in Dec of 1886 wouldn't think that she would have sailed in Dec of 1886 so probably just anytime in 1887. I am stuck on this and would love to have some help!
