Well, I used to have family tree maker, but I lost it in a computer crash earlier this year, so I've been working online. I'll send you an invitation to my tree on ancestry.com. If you're a distant cousin of Katrina's, you're probably a descendant of Commodore Perry Cambridge? He's in my tree, so you may be able to link up to that. He and his many brothers and sisters were from the Willam Cambridge II branch. My branch is from Levin Cambridge, William's younger brother. Both were sons of William Cambridge Hunt(1713-1784) of Worcester County, Maryland. I was recently in Snow Hill in Worcester County and think I located the original Cambridge land there in Maryland. Once you've had a chance to look at my tree, let me know how you connect.
