Hrm I downloaded this tool from onegreatfamily.com and after some playing around in it ended up all the way back to
Sir Robert de Hibburne of Newton
B: 1232
Along the way though there is:
James Hepburn
B: 1536
Spynie castle, Bothwell, Lanarkshire, Scotland
D: 14 april 1578
Gragsholm castle, Denmark in exile
In exile sounds pretty cool....googling for that dude I find its because he had some affair and then married a chick named Mary Queen of Scots.
I hope she was hot
Now this prob isnt really my family tree, these things are never accurate for non-americans...but interesting anyhow
