Did you manage to locate his ship manifest? Was the marriage of your ancestor  to Godec before or after emigrating?

I see several entries for Nikola & Niko Šajatović from Sošice  before 1909  that would be right age for your ancestor - do you know if he traveled to US before emigrating finally around 1909?

Do you know if he were married prior to emigrating? I browsed the records for Sošice Greek Catholic parish that are online, and families Šajatović lived in smaller village - Jezernice, and in several households ( extended family commune called *zadruga*).

At the time your ancestor was born, there were probably several people in the parish and in that village with first name Nikola and last name Šajatović of approximately same age  born and living there in that tiny village - you will need more info to confirm which one you need - like first name of the father, or a name of a spouse in the old country if he were married before.

For first name of the father: people over there never had separate *middle* name - one given at baptism, so if they filled out any paperwork or forms after emigrating they often wrote according to their customs the first name of their father as their own middle name. Be on the lookout for any such document.

One of the people I found in ship manifest , Šajatović Niko, is the right age, born appr. 1875., and on one arrival  in 1902 he is listed as married , and to have previously been in US between 1895-1901. He is going to Cleveland, Ohio. If that is the one you are looking into then you should research the marriage records that are online.

I will post here for you an image of the marriage record  of one of these Niko Šajatovićs from Sošice who was born in 1875, married in 1899 at the age of 24, with notes and surname and first name of the groom you need highlighted, as well as that other piece of crucial info - household number - so that you can navigate these records more easily if you are willing to explore them on your own. Unfortunatelly without more information that can be confirmed, I cannot tell you if this Niko Šajatović born in 1875.  from this marriage record is your ancestor or not.
