I am the son of Bernard Dowty Tootell ( deceased 1949).

My grandfather was Frederick Tootell (approx 1878-1929) who was the son of John who had a glass and china shop in Nottingham.

I understand that John had a brother (Jacob) who emigrated to Australia.

Apparently, John was twice married and Frederick's mother was nee Barnum. Perhaps you can confirm your lineage from the details above and fill in any missing links.
