Hi,
I could not help reading your inquiries, and i just had to tell you that there is a town in Mississippi called Saucier and it is located in Harrison County Mississippi.Maybe there is a historical connection between this town and your Saucier ancesters since they were from Mississippi. Harrison County is also the county where Gulfport is located at too just to let you know the location that i am describing.

Sincerely,

AC Johnson
