Thanks for this information Wallhanger.
My father is suffering from the early stages of dementia but with the details you provided I managed to confirm with him that he is the grandson of Harry Jackson and Ann Lakin.
It was quite emotional to hear him recall that his mother, Martha Jackson, was indeed known as Patti. I imagine he may not have heard her called by this name for perhaps 30 or 40 years. He does not remember her twin brother Harold at all, nor her sister Mary, but all the other aunties and uncles he could name easily.
My fathers name by the way is Kenneth Newton Draper
