I me permet to specify you this wich could be useful for you.
The name of my maternal ancestor born in 1790 in ANDORF (Bavaria) was called JEACKLY Cajeton and became JEGLE after 1810 (I do not know of it the reason). He belived in Alsace after.
His father was called Jean JAECKLY and is decedead in 1813 in Andorf.
