My nuclear family  (Mother and grandparents) came in 1912.  Prague was then part of Austria/Hungary. The male sample from our side of the family is a 60+ yr old cousin.

The sample from the other family who was born in the same village in Czech as my grandfather, (same surname) left due to the 1968 Russian invasion. Both sides have living relations in the old village and both side relatives have said we “May” be distant relatives but no one knows (or seems to care) and details or info about a possible link.

We are really looking forward to receiving the info about the link between the two families. Yes the test will put these two individuals (assumming some sort of match) into a group of 250 who come the closest to matching our samples.
 
Our American branch of the family did indeed maintain communications with the Czech family all during the period 1912-present day.  During the Nazi and Soviet occupation my Grandmother and Mother spent a lot of time fixing clothing to send and in some cases sewing coins into the lining etc to provide support for those in need in the old country. I don’t have the language skills that my Mother had, so my communications has been thru written letters and email, save for some personal visits with Czech family who vacation here at times.
 
For the past 15 years the gentleman who is the sample for the “other family” has assisted me with translations of notes received in Czech.  We get along quite well !
