Suz, thank you so much for trying to help me. I really appreciate it

I'm going to put all I know in one post for you

May was born on 7th May 1892. She married Lewis Waring Robbins on 08 Nov 1924 in Blackpool, Lancashire. She died in the first quarter of 1983 in Kirkham, Lancashire, making her 90 years old.
I believe she had a brother called Sydney, who was born c1897 and died 26 October 1917 in Flanders, France. I have his Dead Man's Penny from the war and the details of his death are on the CWGC website. Now, here's a thing.....
On the CWGC website, it says that Sydney is the son of Mrs Rachael Lewis of 6 Fleet Street, Blackpool. However, because I couldn't find a marriage that 'fit' that spelling of Rachael I was thinking maybe it was a spelling mistake. The Rachael you found is a possibility but there's no mention of May or Sydney. Also, I can't find anything that 'fits' in the 1911 census. It's so frustrating. I feel like I'm so close but so far away!!
Does any of this help at all? I know sometimes different people see different things. There's probably something glaringly obvious that I've missed!!
