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

This website was developed by the Mammoser's from Chicago, Illinois, more specifically, John, Jr. and his wife Kay (Brennan), their sons John III and Kevin, and John's wife Laura and Kevin's wife Anna.  Please feel free to browse the links on the menu on the left to learn more about Mammoser ancestry, and the extended Brennan ancestry, or the personal pages of John and Kay, Kevin and Anna, John and Laura.
