Hi,
I'm Kristian Dabovic Stenstrom and I live in Sweden. My father Jozo Dabovic were born in Kostanjica in 1935 but emigrated to Sweden in the early 60's. His father Nico would have been in the same age as your relative, could there be a connection? Anyway my father had approx 10-12 brothers and sisters but everyone except one have passed away now.
I went there with my family in 2012 and 2013 to meet my cousins and also my aunt Jela.
I'm trying to find out more about my relatives in Montenegro but I find it quite hard to get any info, still I got some from the cousins that I write to.
Maybe you could find out something more from my info and also I tried to name them I know in my family tree.
Best regards
Kristian
