My ancestor is laurentius Sturm who died in Mundenheim in 1813 or so. His wife was Barbara Engel (1774-1843). I've been unable to confirm that Christian was the father of Laurentius. Also, I've documented that Laurentius' grandson was Joseph Sturm (1834-1890). He was married to Clara Eisenacht (1830-1896).
I've tried familysearch, ancestry.com and Gedbas.de.. not much success confirming this info. Any help would be appreciated. Thank you
