The coat of arms is part of a tombstone, now built into the western exterior wall of the Brezovica parish church to the left of the entrance. Franc Preschern (1802–1887), a local mayor and tavernkeeper from Brezovica pri Ljubljani, had it constructed for his parents in 1864, three years after receiving confirmation of his noble rank (1861). His coat of arms is identical to that granted in 1724 to Johannes Baptista Preschern (1680–1746), a doctor of law and clerk at the Carniolan court of the nobility (Germ. Landschrannengericht), on his ennoblement, together with the predicate Heldenfeld (he himself took over the coat of arms from his homonymous uncle (1656–1704), a cathedral provost in Ljubljana, the first president of the Academia operosorum Labacensium and a member of the Society of Saint Dismas). Franc Preschern attempted to demonstrate (albeit with weak arguments) that he was the descendant of the lawyer Johannes Baptista Preschern and therefore eligible to use his coat of arms and the predicate Heldenfeld(t). The coat of arms is also carved on the tombstone of his last descendants in St. Leonhard’s Cemetery in Graz.
