Hi Carole,
The history of Hoghton is very much connected with the De Hoghton family. See;
http://www.british-history.ac.uk/report.aspx?compid=53065 -- or simply Google 'Hoghton, Lancs History' (without the quotes).
Whether the village is named after the family, or vice versa, I am not entirely sure. However they owned much of the land around their home -- Hoghton Tower -- which still exists. It is reputed that James 1 knighted a joint of beef on his visit there - and thereafter such a joint was named 'Sirloin'. There is an old pub in the village named 'The Sirloin'.
I do know that at one time the De Hoghton family were Non Conformists. I wonder if Jane Blackhurst's father worked on the De Hoghton estate -- and therefore worshipped accordingly -- as his master would have wished -- in the chapel at Hoghton Tower? A bit fanciful I know -- but I'm clutching at straws here!!
I find it interesting that your Jane converted to the Mormon beliefs in 1837. It was in this year that many conversions took place in Preston -- and all were baptised in the River Ribble. I believe these were the first Mormon converts in Britain (although I may be wrong about that). However -- if Jane is named on that list -- and in view of the Mormons' strong feelings about family -- isn't it strange that her maiden name was not recorded at that time.
I have done a 'blanket' search of Lancs On Line Parish Clerk site looking for burials and marriages of people named Blackhurst, both before and after Jane's birth. There don't seem to be ANY at all around the village of Hoghton. The majority are from the Penwortham, Croston, Halsall areas -- which are all on the other side of Preston from Hoghton.
I know this doesn't help you with Jane's parentage, which remains a mystery. Sorry I have been unable to assist.
Regards June
