Legacy Membership

Legacy status is granted to each child (male or female) who graduates from a Jack and Jill Chapter and whose mother is a member in good standing at the time of the child’s graduation from the chapter. Once the child desires to enter Jack and Jill through their Legacy Status the legacy will be verified through the chapter by completing and submitting the legacy application which is located below.  The application should be filled out and forwarded to the current chapter president of the chapter in which he/she graduated out from. If at the time the chapter cannot verify the legacy, the chapter files at headquarters will be researched to verify Legacy. If a Legacy certificate was filed for the child it will be in the Chapter Files in Headquarters.
