I have just caught up with the recent posts. I'm glad that the timeline is OK and thanks to Gazania for suggesting it (an excellent idea especially now that the thread is so long) and also Heywood for making a start on it.

A question:
Is anyone chasing up any possible workhouse records? They are at Nottingham Archives. Is anyone visiting or know anyone who might be kind enough to pop along and do a few lookups for Carol? Keep in mind that Harriett was with Alice in Basford Workhouse in the 1901 census and in 1911 she was in Bagthorpe with Alice and John. I think we really need to get hold of these records.
And for Carol:
Mary Ann was 10 when she went to Canada - she must have had memories from her time in England, perhaps not the early memories, but memories of her time in foster care. Do you know if she ever told anyone about her early life? (Not that this will help in the search, but I am just interested). I think after spending 6 years with the Owen family, it must have been very traumatic for Mary Ann to be returned to Barnardos.
At a later stage, I wonder it it might be worth following up on Norman Williams who in 1909 must have gone to a lot of effort to send a letter to Mary Ann who he thought may be his sister. What leads him to believe this? His surname is Williams and her birth surname may be Fisher? He must not have known this and was probably mistaken believing she was his sister - Mary Ann Williams would be a fairly common name I think. He must have been so disappointed that she was unable to tell him anything.
