I guess the surest way is to get his birth certificate to find out who his parent/parents were.
Sep 1866 Tiverton 5b 391 Tola Melhuish
Yes though I was hoping to do this at the moment without the expense of acquiring the birth certificate.
where do you see Tola as a Griffiths? Both are in the same households in 1891 and 1901, and both are Melluishes on the images.
On the 1891 census found on FindMyPast they are all living together - Tola is stated as a Griffiths on the transcription - but just checked the image and he's there as a Melhuish! Ah that makes more sense now (yes yes I should have checked it before
).
Is the younger Tola the son of William and his first wife? He is listed as married on 1881 and 1891 - and with a Sarah Melluish, even if not listed consecutively, and there's a marriage in Newton Abbot district in 1874
From that 1891 census it does look like William was married to Sarah before he married Catherine, perhaps that is them who married in 1874 that you have identified. With the age difference, it seems more likely Tola is Sarah's son than Catherine's. And Emily is probably Sarah's daughter - I wouldn't be surprised if their "A" initials were the same name.
Quite why Tola is "nephew" on the 1901 census though, I can only think to distinguish that he's not Catherine's son, it wouldn't be the first time I've seen the wrong relationship stated for something like this.
Thanks for all your help
seems one of the rare relatively simple branches of the Melhuish tree
