Hi
James Willetts (b 28 Jun 1835) was my great Grandfather's brother. They were both illegitimate sons of Elizabeth Willetts, my gg grandmother, born in Yorkey, Forest of Dean.
James married Harriett in 1858.
In 1871 census, James and Harriett and children were living in Yorkley, West Dean, Gloucestershire.
In 1881 cenusus, they were in Blakeney Hill, in the district of Westbury on Severn.
In 1891 Wales census James Willetts (Spelt "Willitts"), widower (Harriett died in 1889) is shown living in Cwmsifiog, New Tredegar with some of his children.
(My great grandfather, John Willetts, and his family also moved to Wales and lived in Machen.)
Hope this helps. Let me know if you need any more info.
David
