Wow thats great:do you by any chance have the value for marker 390.........its a really key one that delivers a lot of information.
I have done a great deal of study on variations of this last name:
the 1600s were years that a great number of French Huguenots were forced to flee....and an awful lot of names that sound French but arent spelled that way: both in Holland and Germany........were in fact French in origin....as both these countries offered refuge to Protestants.
Thus there are quite a few dead ends for folks searching during this time frame for ancestors......and its curious.
The reason being these French had to basically flee with the clothes on their back.They would make it to Holland and Germany and Switzerland.......stay for a bit: until they could get funds together.....and then usually made their way to a seaport like Amsterdam.....or one in England....and headed off to America or other destinations.
It only took a few generations for the country of origin to be thoroughly disguised and lost to future generations: so grandchildren might not ever know they were originally French......and would assume a full German or other national identity.
The LeSueurs of Normandy were one such family clan.......so one wonders if indeed your lineage is linked to this line:
So DNA is nearly the only way to establish family roots for many........and it yields a great deal of information.
Perhaps if you do have 390 I can shed more light on things for you.
