My maiden name is Heather McIlwain... my whole side (McIlwain side) lives in Louisiana. What part of Louisiana do you come from? We live in the Northern part, Monroe. To my knowledge I do not have any cousins or such that were given up at birth. You are roughly my age and I would assume you, or your family, would have been mentioned. However, it would still be interesting to find out if you are some how related!
