I am pretty sure that we are somehow related down the line. Everything that you wrote matches up to what I have; I just didn't know about the siblings of Amelia. Sarah J.(Jane) Jackson was born on June 16, 1868 in Ashton Under Lyne, England. I do not have a DOD. Her husband, Frank Jackson was born on July 3, 1866 also in Ashton Under Lyne, England. That is as far back as I have just from papers my mother had in a strongbox. Hope that helped a bit.
