Hi,
Welcome to Rootschat

.
I would start by suggesting that you obtain a copy of the marriage certificate. I have just had a look on the FreeBMD -
www.freebmd.org.uk - and this seems to be the reference for the marriage. Certificates can be ordered from
www.gro.gov.uk and they cost £7.00 each.

Elizabeth DilworthCatherine Doohan
Michael Hopkins
The certificate will give you the name of both Joseph's and Elizabeth's fathers.
I can only see one birth in Lancashire for that date and it is in Chorlton not Eccles

(not that far away from each other though).

The birth certificate will give you the names of both his parents and also the maiden name of his mother.
Have you searched for them on any of the census' yet? If you have post what you have and hopefully Rootschat can fill in the gaps.
