Good idea about obtaining the death certificate.
Been on-line this morning (WAY too much time researching). I found in ancestry.com the death certificate for Mary/Marie's daughter (my mom's sister who died in Illinois at age of 14 in 1922). Certificate indicates the mother's birth place as Serbia. So I have a birth place of Bohemia, Czechoslovakia, Yugoslavia, or Serbia for Mary/Marie Gaspar/Kasper married to Henry Vocelka. A GOOGLE search resulted in finding a Bukovac in Serbia and also the following place: "Bukovac, Perusic, Hrvatska, Yugoslavia" which is the closest I have come to the "Spice Bukovec, Harvart, Jugoslavia " listed as the birth place on Marie Vocelka's death certificate in ancestry.com!!
I'm off-line for Easter.
Thanks for all your assistance.
