Hi, I have been researching "Priddis" for many years and have a database of 4000 entries. Catherine Priddis married in Brighton in 1868. The registration quarter was September, Volume 2b, page 265. This seems to be the only likely marriage. The only likely birth for this Catherine in Brighton was 1845, March quarter, Vol. VII, page 289. The above information is sufficient for you to order a marriage and/or birth certificate from the Family Records Centre, London.These would give parents names and occupations on birth cert. and father's name and occupation on marriage cert. for both bride and groom. Contact me further if you like. David
