Dear Tatjana, I am david Horwat (born in 1977) from Pont-à-Mousson in France. In fact my lastname spells HORVAT but a mistake occurs when the identity card of my grandfather has been made. My grandfather joseph Horvat (1913-1993)came in france near 1939 from the village of Raskvyzje near Ljutomer. His father was called martin and I wonder if there is a relationship with the uncle of your father. Some differences seems appear because my grandfather had 3 brothers (Avgust, François and stephann) and 3 sisters (Maria, Magdalena and Hanika), in your message to Wolfgang you mention that the martin of your family had 14 childrens. In addition I thin k that the date of birth you propose for martin (1901) cannot coincide with the situation. however, the proximity of Ptuj and Ljutomer and the identity of the firstnames makes me wonder if there is a link. May be do you have heard about HORVAT in Razkvyzje. I have an adress, it could correspond to the farm my family had: RAZKVYZJE 48 LJUTOMER. If you have some informations don't hesitate to contact me. Sorry for my bad english.
