That's interesting, many thanks Donna.
John Howard Meller was Julia's brother, bapt.16 May 1825 Braddan, but I can't see a burial for him in Brian's index, and unusual for the MI not to have a date.
From the MI it looks as though it was he who went/returned to Wales, and Richard b.c.1778 on the adjoining MI was related (uncle?). He was a similar age to their father John Longford Meller (b.1780-83).
I can't find John Howard Meller (not with mother Christian & sister Julia in censuses), or when he died.
