First of all let me express my condolences on the loss of your Grandfather. Nothing can replace a person who has been there, not only all your life, but way before you were born, there in the family and out there in the world, making his mark.
I think I can help put something meaningful together for you.
I have recently worked on a personal memoir and my client was happy with my work.
I understand that this is probably required very quickly - so, get in touch as quickly as you can. I will need as much detail as you can give - even the odd personal recollection, together with plain facts.
You can call/Skype at a time to suit you - I am in Northern England on GMT (Greenwich Mean Time) but we need to organise first.
My name is Patricia, I'm 61 yrs old, a retired schoolteacher/Civil Servant. I understand what life was like for my own and my parents' generation, (even my grandparents - takes us back to 1880s!) So I have insight into life a way back that might help.
Looking forward to hearing from you. You take care.
