Does anyone have any information regarding the Lemenyi David Family or the Elfer Family. My great grand mother was Margit David de Lemenyi (Lemenyi David Margit) and she married Aladar Elfer (Elfer Aladar). The Town of Lemenyi is in Covasna County and is now known as Lemnia. If anyone has any information regarding the family then I would be very greatful. I attatch a crude representation of the family crest of the David de Lemenyi Family.
Many thanks,

Jonathan Elfer
