Hi Vicki,
I am connected to practically every family in Triggiano and I am probably your cousin too.
If your Nicola Ottolino came Feb 26 1910, it lists him leaving his mother Elena. I have a spreadsheet of all Triggiano civil marriages and I only have one Ottolino married to an Elena anybody during that time frame.
Vincenzo Ottolino married Elena Rubino Sep 9 1883 in Triggiano.
I don't have parents for these two yet but when I get them I can connect back into my existing research. I connect to a bunch of Ottolino and Rubino and my acnestry goes back to the late 1600s.
I will contact you when I get the parents of these two and I hope you will write me privately to discuss the connection and exchange gedcom./FTW files.
