I am looking for information on a Mary Laurie Bell (mamie). My gr grandmother showed me a famil photo of her with Alexander Graham Bell and his mother with a (hearing horn)? And many others. Any information would be appreciated

According to what I find her first name was Mabel, not Mary Laurie, and she was from a wealthy family, the Hubbards. I found reference to a Mary Laurie on another site but that appeared to be a daughter or relative, not his wife.
