Hi Brolga,
I'll put my tuppenceworth in too as Janet/Jane McGeorge married to John Barkley was sister to my ggg grandfather James McGeorge b Parton . Their parent's were Walter McGeorge & Helen McLellan So if you go to the Kay reply on the 'McGeorge' chat and contact her she is a member for the Guild of One Name studies- doing McGeorge name.She's got tons of info
Also when I joined Genes Reunited and put my tree info on(am I aloud to mention that on this site??

)I was contacted by Alan in Australia who's doing same tree(McGeorge/Barkley). His line is through Katherine Barkley (sister to Agnes Barkley who married James Robison)He has lots of info on Barkley family (And Kay has too)but, unfortunately nothing to add on James Robison. (Good work by Monica can I just say.)
John Barkley's parent's were Hans Barkley and Kathern McRobert.
John & Janet had 9 children.
James Robison had another 3 children :Janet b 1863;Walter b 1867 and Mary b 1869
Too much info to write it all down here. I've told Alan to take a look at this chat and he'll get in touch with you too I hope.
Keep up the good work people.
Linda
