My Granfather (who has since died) had researched our family tree and discovered that we're related to General Elliott who defended Gibraltar from the French and Spanish in the 18th Century. His daughter also married Sir Francis Drake, who is a pretty cool guy to be indirectly and distantly related to.
Unfortunately he didn't seem to leave any working out, and my modern day attempts have gone back through our family by a couple of generations but nowhere near the 18th Century.
Is it best to work back through my family to try to get that far, or to start at General Elliott and work down? It's difficult to know which branch of the family to follow and our general knowledge about our ancestors only goes back a generation or two.
Is there an online resource I can make use of?
