Rona, A few years ago I received a brochure from a company that researches names and family crests. It mentioned that the first record of Di Giacomos in the USA was in Arkansas in the 1800s. That is where I got the information. I don't remember the name of the company or the first name of the Di Giacomo that settled there. I was surprised. I didn't think any Italians went to Arkansas. At the time,I thought it would be funny to hear a Di Giacomo with a Southern accent: "Coma sta?, you all." Well, that is all the info I have on that.
