Rumtaya said:Well that might be the case but in most cases you can still track an ethnicity by knowing what church they was part for (either armenian or assyrian) and also the language he would probably speak or your grandfathers perants or grandperants. Always a way to trace them. Alongside that you would have his original name and family clan name.
Yeah these are all significant factors and could be used to determine the ethnicity, though his name is an Islamic name because he converted as a kid (his whole family) next time they/I phone I'll ask.
