You have more info than I as far as the Leatherbarrows.
I was 3 when my father was killed in W.W.II.When I became interested in genealogy, there was nobody left in Canada to help me and I didn't know of any sisters and brothers in the U.K.
Here is what I have.
Thomas Henry Leatherbarrow married Lucy Eckersley in the U.K.They had three children, Ruby, Tom, and Norma.My father, Tom was born on Sept. 10, 1910 at 102 Weston Street in Bolton.They immigrated to Canada when he was a young child.I have never heard of Banbury or West Derby.
The Hayes' didn't enter the picture until my Dad married my Mom. Marjorie Hayes in 1939 in Canada.
Thanks so much for what you have given me and I hope if you have any other info you will pass it along.
