Hi Yolande,
I am a descendant of Bernardus GUIDINGER as well ( 7th generation). My great great grand mother was Anna Maria GUIDINGER born 27 January 1795 daughter of Nicolas GUIDINGER 17 November 1749 and Marguerite KIEFFER (1766-1809), one of his 3 wives. I descend through the HENGEL family then into the LOMMER family, both families moved to Paris France after the Napoleonic wars where both families served in Napoleons armies.
Cheers.
