hi, i'm looking for info on lukac / marusak from Slovkaia or Czech Republic. My ggrandfather was Michael Lukac born in 1889 in "Slovakland" and moved to western PA in early 1910's. His wife was Anna Marusak, b.1897 in Slovakia. They had 6 kids, all but 1 born in PA. They settled in Munhall. I'm looking specifically for the village(s) they were from and possibly their parents / siblings. Any help is appreciated. I'm stuck!!
