Hello Chris,
I have somewhere, a letter re a Minnie Thickbroom who died leaving money to her brothers and sisters, who having died their share went to her nieces and nephews - my Dad being one of them. Tomorrow, I will sort it out and try to scan it to you or if you let me have your address via email I will post to you. Your grandfather also had a brother, Tom who was married to Auntie Nell. They had two children, Linda and Colin. I will email my addy to you.
Speak more tomorrow and thank you very much for your help.
Best Wishes, Lynne
