Hi aelliott and welcome to "Gente"
You may have noticed that I moved you post from the 'Translations' forum to this one as I felt it would attract more attention and help on 'Where do I start'.
We have some really good researchers here, but bear in mind it is summer and many are on holiday at the moment.
Do you have any other information on Andrea? His date of birth, wife's name? Anything at all, no matter how small can often be of use when searching archives, ships lists etc. so don't hold back.
I look forward to following your search with us here on "Gente" - good luck!
