Almanzo was almost exactly 10 years older than Laura was. Almanzo was born on February 13, 1857 while Laura was born February 7, 1867. When they married, Laura was eighteen years old and Almanzo was 28.
While by today’s standards, this age difference can seem quite significant, in the 1800s, it was much more common for women to marry much younger and for the husbands to be older.
Laura’s father, Charles Ingalls, was also several years older than her mother, Caroline Quiner Ingalls.
