I have a birth certificate of Rose Ann Cain, born 9 April 1856, registration district West-Derby, subdistrict Toxteth Park, County of Lancaster.

The parents are given as William Cain, joiner, and Bridget Cain, formerly O'Neill. Their address is given as "Mary's Place, Robert Street, Toxteth Park".

I am unable to find this couple in the census; neither can I find their marriage.

Any help will be very much appreciated!
