Hello Gerald, have you seen the baptism of John Evetts, 22 November 1854 Kenilworth. Father Joseph, mother Esther. they also baptised Alice Evitts 8 July 1857 and Joseph Evetts 22 November 1872.
I found the family in 1861 in Kenilworth, living in Chinton Lane.

Esther age 31 born Gloucestershire, Shinnington
The children were

Then they disappear, I can't see them later than '61. I will look again tomorrow.
