I appreciate the time spent on Joseph Hozack, thankyou. The thought has accured to me that it may be that Joseph was not in the country on census night as he was a dock labourer and I have a feeling that he also worked on ships as a Stoker. I wonder if a look for Margaret Hozack would be more fruitful. She is the one that is recorded on the 1864 birth certificate at 1 Back Pilgrim Street, and then again in 1870 at 13 Denbigh Street. I have also realized that Margarets son was Joseph Hozack b. 1855 in Ireland. It may be that the family could be traced through him. Hopefully he will be with his mother Margaret somewhere in Birkenhead. Thankyou, Kathryn
