My DH was named after an uncle Glen. One N it gets my DH upset if people spell it with 2 n's says Glenn is NOT his name!
DH insisted on nameing one of our boys after himself. so we have Glen Wayne (DH and Glen Wayne II. We called our son Little Glen the whole time he was growing up. He is now 6' 3" and had twin sons. When Devon was 3 I called his dad little Glen. Devon looked up and up and up at his dad and said "He doesn't look LITTLE to me!" LOL He is still little Glen to the family or GW
My DDs inlaws - FIL's father was Cleo Jewel and so FIL is Cleo Jewel II and one of their sons is Cleo Jewel III. FIL's dad was called Joe and FIL goes by Cleo and of course Cleo III is called Little Cleo tho he is 6 ft and overweight. It does cause some confusion when talking about them!
