At last there are people (Jellie's,Jelley's,jelly's,Gellie's, and every other combination of spelling. I am living in New Zealand and an uncle of the Maria Jellie who made contact in 2006. I have been researching my Jellie family history and have gathered quite a lot of information some of which is very interesting and some of which leads to a dead end.
I will be posting all of this soon but not tonight as it is bed time.
As a teaser: My great grand father came to New Zealand in the 1860's from a town in Northern Ireland called Ballydrain, which is situated on the shores of Strangford Lough just south of Comber, just south of Belfast. The cemetery on Tullynahill Rd in the area is full of Jellie's and all other spellings. Our name was originally spelt Jelly but was changed in New Zealand to what it is now.I do not know the reason why. I visited there a few years ago and found in a church in killinchy the baptism records of David Jelly, my Great grandfather, 1 of 10 children who's parents were James Jelly married to Rosanna Bishop of Comber.
I have not been able to go further back than that or tie them up with the family trees that have of other jellie/jelly's. This forum may open the flood gates of information. I hope.
