Hello!
I just found the birth record for my 2x great grandfather George Muska (b:1848 Kyiv) and it listed his parents as Pantelemon Davydov Muska and Agrippina Titova. I however have not been able to find any records on them. I think Pantelemon was born in Greece because of his first name and my DNA showes someone in his era was from Greece. Pantelemon and Agrippina were probably born in the 1910s/20s. Agrippina was probably born in Ukraine.
Thanks!
Michael
