My father was born on 11th January 1892 at Nagyperkata, now Perkata. He was named Kellner Jozsef, but changed his name to Kalman. He died in 1981 in London.
His father was Kellner Bernard, called Pal by everybody. He died in Budapest in August 1941.
My great-grandfather's name was Kellner Matyas, who had 6 children from 6 wifes. 1 son, Jeno was the first officer lost in WWI, he had three sons, one of whom lives in NY State, aged 90.
Matyas had a forebear, a Roman Catholic priest, who married a Jewish gorl and was ex-communicated. I saw the couple's grave in Hungary, just outside the consecrated grounds of a Catholic cemetery, but cannot remember where.
I know of just one more Kellner, a female called Ilonka, whose descendants are a distant relation of mine, but I do not know where she came from.
As you probably know, the "Kellner" name suggests that the family came from Cologne, Germany, thus Kollner, later Kellner.
