Thanks for your informative reply. Sorry it has taken me so long to get back to you.
Shame about the Jam connection ! Although I still have the chocolate one to be getting with :-)
So, now that you have connected the Hellabys, Robertsons and Gosnells for me, I only have one further question : can you fit John Menzies Robertson - business partner of Alfred Ernst Gosnell - into the equation ? Perhaps a brother or nephew of Isabella ?
If there is anything further I can help you with on the Gosnell side, please let me know and if you happen to come across any further information about the Hellaby/Gosnell line I'd appreciate your keeping me up to date.
