Barry, I’m wondering whether your knowledge of the existence of Isabelle Louisa (Lily) Clague comes from details known within the family before you started researching Edward Clague b 1879. Or is it possible that Lily’s details entered the picture from your research or from the research of another family member ? What I’m trying to ask is ----- can you be absolutely sure that Lily was the sister of your Edward Clague ? Did they stay in touch once Edward and Mary Ellen had emigrated to Canada ?
