Thank you to everyone for your input!! It's definitely not something I'm rushing into, I'm just searching for ideas. I don't want to go into detail like a portrait, because personally I just don't trust tattoo artists enough for that. Also, I want something more original than just birth/death dates.
My father did not actually live in Switzerland or speak the tounge, but our last name however originates from there. I thought it would be very nice to have a meaningful sentence in the language that our name belongs to. Unfortunatly I cannot find exactly which part of the Country it originates, all I know right now is that the meaning of it is fence, or boundary line.
Thank you all again for your suggestions! I will definitely put more research into it before I make any final decisions!!
