A lot in common, hmm? How much in common? :P

Mine also happens to be the second child of a mage family who ended up with her family's Crest after the loss of her elder brother.  And her Servant is a Rider.  So a lot... to the point where I am seriously considering putting her on the back shelf and bringing back a Master from an RP that never got off the ground.

(however, I will note that Marguerite--my Master--is almost 10 years older than Alexandria, is American, and her only living family is her mother, so there are some differences.)
