Did Robert the Bruce have any children?
Loads of people can be 'traced back' to possible notable ancestors but the 'connections' are often of dubious quality. We had a Great Uncle who was keen on genealogical 'research' and apparently our family on his side has William the Conqueror as an ancestor. I doubt it!
On the other hand, by the time you've gone back, say, 6 generations (200 years?) you've at least 64 direct ancestors; if you're going back 800 years it will be into the 1,000s from all over the place. So a vague possibility that there may be a notable or two in the mix...
I wouldn't let it worry you, paddyann; it's probably not true
