Castle Obsession?

All right, let's ruin the suspense for you mystery buffs out there and get right down to it.

Castles: what's up with that? Well when I was, younger, shall we say, I saw every day a piece of wood with my last name on it with 5 castles on it. I was told this was our family's coat of arms.
We even had a geneology with that "ensign" emblazoned on one of the pages. You could tell it was a real geneology because it also had other coats of arms attached to our family.

See, back when a coat of arms was like your company logo, your family's logo identified you in the real rat race of life. It was your personal statement! Today most of us assume it identified all the succeeding generations down through time. Not true, unfortunately. Your coat of arms was truly personal. Each generation or person had to earn their own from the crown of (in my ancestor's case) England.

So, even though 5 castles were on the coat of arms of the ancestor of mine who came to America
way back in the 1600's, I cannot claim them. I can only dream! And wonder, which 5 castles were they?
