Oh my! Thanks Len, I missed this one totally, having looked for Elizabeth Gicks and John Christians only.
Jane was presented in the Church Court in 1867 for having had an illegitimate child. No father was named, and apparently no action was brought against him. I have taken this child to be John Christian, and the Gick connection was, I thought, just tidying up.
I am now wondering if perhaps that illegitimate child is Elizabeth Skelly (Gick) and thus my John Edward Christian would either be another illegitimate child born to Jane the next year (1868 fits best for John) or perhaps the child of one of Jane's sisters or another relative. It seems that he was not christened but having missed Elizabeth, I wonder if I have missed something else.
Thanks, I am very glad to have this insight and information, but it's back to the drawing board for me now :-)
