I am reading posts from several years ago, so you may be up to date at this point. Paula Collins wrote in 2010, but I didn't read her post. Her grandmother and my great grandmother were sisters and two of the eight Cadogan sib's who came to Boston. My GGM Mary Ellen Cadogan, along with her brother John/Jack, were the first in about 1878. There is lots of info on Cornelius and Julia and all the children. I have made contact with a great granddaughter of Katherine, one of the two youngest who married a British man and moved to London. I'm trying research my Cadogans in Boston, i.e. their descendants. There must be thousands. Please write if you get his.
