Firstly a big thank you to everyone for their time and effort. I hope its okay if I reply to all mesages in this one post.
Cora Collinson living with Bennett family ia a yes. She marrried a William Bennett in 1901 (found on BMD) and was the only surname my mother could remember. I'm assuming William Bennett is the son of whom she was boarding with.
Sarah Jane Collinson at Ledsham is a possibility, but if Cora is with a relation in 1891 why not Sarah Jane, she may be a niece to my Walter Henry.
Eliza Collinson in Brotherton does'nt feel right, daughter Eliza would have been on the 1881 Census with Walter Henry and Eliz, I'll check her out on the 1881 census.
Now the water becomes muddy, the reason I am desperate to find Walter Henry Collinson is that I have seen this information about Eliza marrying a Steel on a family website, I am conviced this is wrong, but open to correction. My grandmother Cora Hall (named after her aunt Cora Collinson) knew her grandfather albeit it as Henry and from Morley, my grandmother was born in 1901, just made it on to the 1901 census, which is how I know the family was originally from Kippax.
I hope you are all still with me, I know it can get confusing following other peoples relations.
I did ask my mother before she died if her mother ever talked about her grandmother and she said no only her grandfather. It is possible Walter and Eliza separated (no divorce then of course) or Eliza had died.
I have found on BMD (what would would do without it) the death of an Eliza Collinson Dec Qtr 1896 N. Brierley aged 36 the district is near enough to the others to be in contention, only why was Cora with the Blackburns in 1891.
I shall follow the leads you have given me, but I fear Walter Henry has escaped again.
