I do not know of a Robert. However, my maiden name is Bajcar. My father's first name was John (WWII), my grandfather's was Joseph (WWI), my uncle's was Joe (WWII), and my other uncle was Victor (WWII). All are deceased now but had the unusual name of Bajcar. My grandfather, Joseph, and grandmother, Maria, immigrated to the USA before World War I. I grew up in Ohio and visited relatives in Abraham, Czechoslovakia around 1987 after writing to them from an address I have from an old letter.
Look forward to hearing back from you.
