Need a translation please

[Big Mikey]

Using Google, I came up with "family"- clann, "important"- tabhachtach. Might be close?

[The Wizard of BC]

What we're looking for is not a literal, word-for-word, translation but more how would an Irish Gaelic speaker would say the phrase "My family is the most important thing in my life" or some short phrase that conveys the same message.

Or in other words if there were a Clan Crest Badge with the motto in Irish Gaelic that meant "Family First" what would that phrase be?
