I've found this family on other census records, but no luck on the 1861.
Thomas Frederick ETTERY born 1817 Monksilver, Somerset.
Thomas ETTERY but could be Weatherstone born 1858 Liverpool Eliza ETTERY but could be Weatherstone born 1859 Liverpool.
His children are christened as Ettery, but he does not marry their mother Mary Ann Weatherstone (born 1832 Wiltshire) until 1862 in St Martins, Liverpool.
Not sure if it would just be her and her children or Thomas F as well, presume they should be ETTERY if they were christened that. They have another son born 4th quarter 1861 in Liverpool.

You are a star, I thought (yet again) that I'd tried every combination of surname. I see he was calling her his wife 12 months before they married, the older children are from his first marriage.
