Origin of Clannad's name

[Bredan]

Wondered several times what this name ('Clannad') meant or where it came from, without ever this being important enough for me to search for an answer... and I came across the answer by accident lol : From Wikipedia (last paragraph of 'Musical style and legacy')

Quote

A Japanese visual novel released in 2004, which spawned a 2007 film and a 2007–08 television series based on it, was named after the band because screenwriter Jun Maeda mistakenly believed it to mean 'family' in Irish.

I do not intend to fact check this and will take Wikipedia at its words and live a slightly better life now.
