Thank you so much for your interest in my search. Unfortunately I know that the Mary Alice Wormwell you have identified the marriage for in 1901 is definitely not my lady. My Mary Alice Wormwell had two more children with Robert (after Eleanor), in 1903 and 1905, one of these being my grandfather. I have birth certificates for the later children that confirm Mary and Robert are the parents.
Many thanks for your help though, it is much appreciated.
