Jack and Jill of America was founded January 24, 1938 in Philadelphia, Pennsylvania from a meeting of 20 mothers under the leadership of Marion Stubbs Thomas with the idea of bringing children together in a social and cultural environment. From the beginning, Jack and Jill of America focused on instilling the values and leadership skills that would serve each child well into adulthood. The concept was so inspiring that it soon spread to other cities and other states. In 1947 Jack and Jill of America was incorporated under the laws of the State of Delaware as a non-profit organization. Today, Jack and Jill of America is a nationwide organization with over 225 chapters in seven geographic regions encompassing thirty-five states and the District of Columbia. Membership has grown to over 9,500 mothers and associates, and more than 30,000 family members.
