Hi. Thanks so much for your response. I was thrilled to find an Eleanor Kaighin b 1801 IoM who emigrated to NYC. Here's what I have for documentation (caveat every record spells Crain or Segur differently):
NY City marriage certificate, dated 3 Oct 1876, of Thomas H. Craine (my GGF), age 41, of 101 Lewis, NYC, spar maker, father "John" and mother "Ellen Keigham," and Pauline Segur (my GGM);
1860 U.S. Federal Census for New York County, 3rd Division, 11th Ward, dwelling # 83, "Eleanor Crane," seamstress, age 59, born Isle of Man, and my GGF "Thomas H. Crane," spar maker, age 23, born New York.
I can try to scan & email you documents if you wish. GVS
