Silvery, I admit to being totally confused!
As I understood it, the lady who had died is Thelma, daughter of Mabel Horrocks b around 1911.
The link they want to prove is to Violet, Michmoor's grandmother, born sometime between 1903 and 1909. Hope I've got that right so far.
Violet and Mabel are around the same age, give or take, and Thelma is the next generation down.
Because the 1911 census is the latest we can have a picture of the families I was hoping that something in the Horrocks household would give a link to Violet, because it's possible they were cousins?
The lady full name is Thelma Bridson passed away Isle of Man April 2010 aged 77 or 78.
The key is establishing the relation to my grandmother Violet Moore nee Stephens who died in 1990 aged 85 or 86, there was some relation to her and Mabel.
At the time I thought I was following a logical train of thought around potential cousins - now I think I was just bewildered!
p.s. just saw Eileen's post - if Sarah was Sarah Stevens it would make Violet and Mabel cousins which was what I think I was trying to grope towards (in a rather fuzzy way) earlier
my bit
Joseph Fredrick Horrocks married a Sarah Ann Stevens in 1917,
could Voilets surname be spelt Stevens not Stephens .
