Yes those names are a match - I only have the Vickery line of information as per your grandmothers maiden name. Working backwards the lineage is:
William Vickery & Charlotte Varndell John Vickery & Frances Grinham** John Vickery & Lucy Hurdle James Vickery & Elizabeth Rogers*** John Vickery & Mary Winslade - Crondall John Vickery & Elizabeth ? - Crondall John Vickery & Jane Milton - Bentley John Vickery & Katherine Cawdrie - Bentley 1650s John Vickery - still a work in progress! Think they are back in Crookham.
*** I am a descendent of there son James Vickery ** I am in contact with a descendent of their son John. Others from the family went to Canada and he has a lot of info and is in contact. We have independently verified this same lineage.
I have a lot of info - do you want to do a swap - if so email me on firstname.lastname@example.org. I can either send you a gedcom or a family tree maker report in word. I have no other info on Heathers other than the census info.
