Yes, the first group is from Bella! Gerard (Gerardo) children were Nichola, Livia, Lucy, Camella, Anna and Anthony.
The Eugene I have that I think is part of this family, but not sure where was born in 22 Feb 1819 so he's not the one you mention.
My Nichola (from Gerard) was born 13 Sept 1867 - so that works perfectly into your dates!
My immediate Vetromile family is in Massachusetts, most of close but not immediate Vetromiles are living in Rhode Island and Conneticut - are you part of this group?
Would you be interested in sharing what you have? I'm afraid I wouldn't have much more to share, but I'd be willing to share what I have.
