babynames | A chance encounter at the Chick-Fil-A

We went out for nuggets, and in the play area there was a very cute little girl that was being kind of bratty and blocking the platforms up to the slide. With the intention of modeling nice behavior for my 2 yr old, I leaned down and asked this little girl her name.
A voice from above (Not the little girl herself) answers and says, "Her name is (mumble)-istin." I asked, "Is your name Kristin? Kristin, can you move please so we can climb up to the slide?" The Voice replies with an audible sigh, "NOT KRIStin! WESTIN! Her name is WESTIN." The Voice was Westin's older sister named Parker. They had a baby brother named John.

I can kind of see Parker on a girl thanks to Parker Posey, but Westin? Maybe it was spelled differently...Weston, Westyn, Westan. idk. The girls' names just seemed way to masculine to me, but I wanted to post in here and see what everyone else thinks. Parker's reaction to me calling Westin 'Kristin' makes me think that happens often.
