I am Duane Esser of Alma Center, Wis. I am a great grandson of Henry and Catherine (Lagros) Gilles who migrated to America from Luxemburg about 1850 and settled in Iowa and then came to LaCrosse co. Wis. I am interested in the info mation in your Gilles book. Is this book available and what would be the cost?. I have much Gilles family material and will share this data if you are interested.
