Hello Su, Thomas YOUDS, the son of Maria and Thomas YOUDS, joiner of Irby is one of my YOUDS. I also have Stanley YOUDS and Mary CHATTERTON who married in Liverpool in 1823. I have them with 3 children: Ellen b 1823 Bidston, Catherine b 1833 Bidston and Thomas b 1835 Bidston. This family you have in the 1841 census may well be yours. I hope someone can look up the 1851 census for you to confirm this. I think we may have corresponded some time ago when I put you on to your mother's cousin in Australia. Am I correct? Let me know what you find out. Kind Regards from Anne in Australia. I use, support and recommend the Archive CD Books Project, and find them invaluable for genealogy research.
