As Mudcat search engine hasn't been working, I give the link here to the thread in which the Irish Gaelic words, "Mo Theaghlach" (my family) are posted: https://mudcat.org/thread.cfm?threadid=79301

According to https://thesession.org/tunes/3585 (My Home - I played the first setting and it is the same tune as Mo Dhachaidh, My Ain House, Mo Theaghlach)
"Played at the funeral of Queen Elizabeth, the Queen Mother, said to be one of her favourite tunes."
