The next war of interest would be the Mexican War which occurred between 1846 and 1848. This is a war that is not spoken of much. Soldiers from all over the United States participated. Southeast Michigan was no exception.
Pensions were available to those soldiers who served sixty days and to their widows who did not remarry with a act of congress in 1887. The files are arranged in alphabetical order and have a master index of names. The records are indexed in "Index to Mexican War Pension Files 1887-1926"(T317- fourteen rolls). The files include for the soldier place of birth, enlistment date and discharge records and areas lived in since service. The spouses file will include date of marriage, who married them, and where the soldier died. The file will include wife's maiden name, names of former wives if any with date and place of death or divorce. It will also name all living children with their dates of birth.
