Hi
Ronald,
I don't know anybody named Lugmayer, but I know the name. It's a name from southern Germany and alternative spellings are Luegmayer, Luegmair, Lugmayr etc.
The first part of the name (Lug/Lueg) comes from the Middle High
German word "luoc" which means hole, hiding-place (of the deers). The second part (Mayer) comes from the Middle High
German word "meiger" which means the bigger, higher one.
Regards,
Satu
