...probably not? [He gives a mildly resigned laugh. Though he's not fully certain what Anna's idea of the Santa lore might be and if it differs from the standard 21st century earth perception of a magic old man leaving stuff at your house if you're good enough. Then again Barry knows about it is catching some Christmas specials on in the background during the season (He saw The Santa Clause on a plane once! He doesn't know if the whole kill and replace thing is a Tim Allen original or if that's just how Santas are made!).]

So that'd make her an aunt--or something. ...how old are these kids?

[If it were just Dee, Snake, and some teens he'd be turning it down in all likelihood, but the idea of little kids from the middle ages does soften it a bit. Significantly less terrifying than your average mall Santa (He also saw Elf on a plane once! Mall Santa seemed like a painful job in that movie!)]

I'd mostly just have to let them tell me what they want or--however it worked back then. Wasn't old Santa a saint or something?
