Thanks to both of you for so much help. Yes, I would like to have the 1851 details also thank you.
I did come across another EVELEIGH family in Devon, but the wife was Sarah and they were in Ottery St. Mary Devon, so I think they are not my lot.
Re Richards thought that my Frederick James BAPTIST may have been the stepson of James Joseph BAPTIST and maybe NOT the son of Emma, does this mean that perhaps James Joseph BAPTIST may have been married before he married Emma?

I noticed on the 1881 census that Emma, although 19, is listed as "no occupation" whilst her younger sister, Eliza, who was only 15 is a milliner. Would this be common to have the eldest child not working?
I seem to be going around in circles...... OsbornD
