Yes. Mackenzie has one older half - sister. She is 14 years old and lives with her Dad in LA. They share the same Dad and she comes to visit as many times as she can. Her name is Harlequin Foy and her and Mackenzie look exactly alike. Hope that helps :)
yes she has on brother as said in her MTV nterview with Josh. I think his name is Charlie or Michael because thats what a so called ''Mackenzie Foy" said on twitter but we all know that her fansite says she doesn't have twitter
