Hi sounds a good plan.
So your partners relationship to Henry and Violetta is they are Great Great Grandparents?
If it is that's the same for me, I've had a look at my tree and it looks like their son, my great grandfather John Parker born 1877 was brother to Albert born around 1882? who is I think your partners great grandfather, that's where we split families.
I've also got that there were 9 children born to Henry and Violetta.
I've got that Albert married an Isabel White, does that sound right? the problem is that there are so many Parkers around that its easy to get the wrong marriages and children.
I'm happy to share information, as it took me two years to prove who my grandfather was! The Parker line only stopped at my mum.
Are you on Genes Reunited?
regards
Peter
