“I feel with a peculiar sympathy all that relates to Scotland. The natives of Scotland, and all those who have Scotch blood in their veins—particularly if, like me, they only have Scotch blood in their veins—are not apt to forget the country from which they sprang. They know its great qualities. They know the solidity of its character.”

"Royalty" (1964)
E. L. Wisty
Context: We've all got royal blood in our veins, you know. It's the best place for it in my view. We've all got a little bit of royal blood in our veins, we're all in line for the succession, and if nineteen million, four hundred thousand, two hundred and eight people die, I'll be king tomorrow. It's not very likely but its a nice thought and helps keep you going.

1780s
Context: Neither my father or mother, grandfather or grandmother, great grandfather or great grandmother, nor any other relation that I know of, or care a farthing for, has been in England these one hundred and fifty years; so that you see I have not one drop of blood in my veins but what is American.
