I do not know about florence johnston beyond the age of 13. Can you give me more info about the Hosners?
are you related to the Hosner family. One way to verify if it is my Florence is her birthdate of 31 Aug 1889.
Another piece of verification is if you knew your Florence was associated with ELLEN SHANAHAN or the Shanahan family of Carlton around 1902.
I look forward to hearing more info from you
