So I am looking at getting a tattoo that incorporates my mom, my two sisters and I. My ideas are as follows and I would like translations for all or if anyone else has any ideas I am open for suggestions!
1.family forever
2.a family as one
Thanks so much everyone! I really appreciate your translations and suggestions!

Hi, welcome to ILF.

To get the ball rolling, perhaps:

mo mhuintir go deo "family forever" literally "my family forever"

muintir ar aon aigne "a family as one" literally "a family in one mind/intention"

Await further input ...

No problem, but be sure to wait for confirmation or correction before inking.

I like "Mo mhuintir go deo." You could also use "go brách" in place of "go deo," if you prefer the look of it (both mean "forever").
