Anyone named Quatermain? Or Quartermain?

Factual Questions
1

About Allan Quatermain from Rider Haggard books and the LXG movie… everyone, myself included, seems to naturally throw in an R to make his name Quartermain.

Are there many people named Quatermain? Is it an old English name or did Haggard devise it himself?

And what about Quartermain? Is it common?

(My Googlings have only brought me pages of debates about the comic and the movie.)

That page from the Quartermain family is a treat. I love the phrase, ‘our cousin, once removed by fiction.’

There’s a character in the soap opera General Hospital named Alan Quartermaine. I presume that the writers took the name from Haggard. I don’t see any resemblance in the stories or characters.

There’s a reasonably well-known sports-journo over here called Stephen Quartermain (yes, with the “r”).

There seem to be a coupla dozen Quartermains here in Oz - no Quatermain’s though

Character, nothing, there’s a whole family of Quartermains on GH. Edward, Lilah, Monica, Alan, A.J., Jason, Emily… NOne of them are in the habit of looking for King Solomon’s Mines though, too busy plottin and seducing and whatnot.
