OK , had a recap
We were looking for a birth of Lillian Steele , maybe 1907 (her death indicates that date, by then she was married to Cain)
A possible marriage for father Leonard to an Ellen Read was found in 1910
this would make Lillian born before the marriage
Lillian had a sister Kathleen, also married a cain
We successfully found her birth entry.
Also found an Ethel Steele, with mum's maiden name Read.
Was she another sister - or was the Steele / read marraige not th eright one?
NOW - having got Kathleens birth cert, it reveals that mums maiden name WAS Read -
So
we have now added evidence that
a) the Steele / Read marriage is the right one
b) there was a third sister
c) Lillian was born before the marriage
