Wow thanks for the replies

Walter Charles Sear is my Great Grandfather.
Sorry about the confusion with the moving to Oz part. My Mother moved to australia with her mother Winne Sear and Edwin Sear together with her 2 brothers. After Mum moved to Australia there was not much communication back to england with Walter that my mother knew of.
The money could be accounted for in that Mum has told me that Eliza was said to be very shrewd with money and Mum had been told that Eliza use to sell things (not sure what) on the "black" market during the war time. I have only just heard this last night as I was question Mum about any memories she had or stories she had been told.
Mum also mentioned to be that Eliza had or worked in a coffee shop some where that was away from her home - so who knows what that is all about

I do not know of any "dell" connection but will have a look tonight as Eliza was one of 11 children that I know of.
