I am also related to this person through Nicholas Sturm. His daughter was Mahalia Sturm who married Jesse Ryan. The line goes through the Ryans, Van Cleaves, Booth, Maller to Pelc. Thanks for Johan's birthdate. I only had the year. Do you have any more information on him? I would be interested in information on that book. I have his father's data, and his grandfather's - Christian Sturm. I think that Christian's parents were John Peter Sturm and Anna Barbara. Would appreciate any more info. This is fascinating!!!
