Asking relatives for information that dates past 20th centtury is bad enough. Most families in Greece paid very little attention this type of information. And it was all word-of-mouth information.
Therefore am I presuming when I look up this name? I am not sure. It is worthy to note the similarities in it.
Starting with Tarambanis=Greek, Taramban=Italian, Taraba=Euro/Slavic. As you said, names can change over time and in special situations. Where to go from here, I am not sure.
I just wonder how many people do some other forms of testing so see if certain people are related? For example blood test, etc.
Thank you again for your time. It is truly appreciated.
