Henry David Ferrier was an elder brother of my great grandfather Alfred James Ferrier. He emmigrated to the USA and settled in New York City (Kings County, Brooklyn). I know Henry David had one son who got married and they then had chidren. I have figured out what happened initially to some of them. Most of them stayed in New York State, some moved north to Catskill Town, and Earlton in Greene County. I would obviously like to trace them onwards to a living person. If you are able to help then I would be most grateful albeit corrections,or additions. (Use the contact form in the left column once you have logged on.)
