Mandii Marples-Macintosh

Mandii Marples-Macintosh is Maddy's mom.

She hyphenated her surname upon marrying Mac Macintosh, but he did not do the same!

https://www.bcdb.com/cartoons/Other_Studios/M/March_Entertainment/g2g_Got_to_Go_/ refers to her by just her maiden name "her parents are big TV stars -- her mom, Mandii Marples, hosts the top-rating showbiz report "Celebri TV," and dad Mac Macintosh is a famous globetrotting journalist." despite Maddy calling her mom "Marples-Macintosh" unlike calling her dad "Mac Macintosh"
