Betty - I have two documents which establish some of the relationships of the BOLLA family, at the turn of the century. The first document is the 1950 Last Will & Testament of Rosalia Bejczy (BOLLA). In it, it names Albert G. Bolla as her brother, her sister-in-law Julia BOLLA, first cousin Charles TOTH, grand niece Rose Crawford (my mother) and Sandor TOTH Sr. of Szekszard, Tolna, HU.
The second document is the 1902 manifest of the S.S. Kensington, which lists Rosalia BEJCZY (BEJCZI) with her husband Sandor BEJCZI and her brother Karoly BOLLA (1887). They were going to see Rosalia and Karoly's father, John BOLLA in Del Ray, Detroit, Michigan.
I have these documents available for viewing on my website. Also pictures of Rosalia, her nephew Nicholas WOLF (FARKAS), her niece Ilonka FARKAS, and grand-niece Rose CRAWFORD (KUHN).
