Welcome to Mammoser.com.  With a unique name like Mammoser, we are all related somehow.  There are Mammosers all over the United States, from California to New York, New Mexico to Minnesota.  We all came “across the pond” via Christian Mammoser of Schoenenbourg, France.  The genealogy of the Mammosers, Brennans and related families can be found in the family trees on the left.

This website was developed by the Mammosers from Chicago, Illinois.  Please feel free to browse the family tree links on the left to learn more about the Mammoser and Brennan ancestry.

If you are a member of any of the family trees and would like to be included, make additions or have corrections, please e-mail me at kayb48@yahoo.com.
