My name is Karen Walker and my husband's grandfather was your uncle with the grape juice business. It was called Walker's Grape Juice and he eventually sold it to Welch's. His name was William Homer Walker. He was also, at some point, the dean of the law school at Tulane. He came up with the idea for federal savings and loans and chartered the first one, which was in Miami. The family lived in Miami when my husband was growing up and some of them are still there. My husband's father was named Joseph Henry Walker and he moved his branch of the family to Orlando sometime in the late 1970's. His kids are spread out all over the country. We live in Boone, North Carolina. Let me know if you'd like more information and I'll get my husband to contact you. You can find more here :
