Henry L. Mousel was born within a year of his brother in April of 1878 at the family homestead near Cambridge. As brothers Henry and Robert shared common interests in livestock, and would attend many livestock shows to admire the cattle being presented and shown.
Henry L. Mousel married Miss Mavel E. Welty. They had seven children, Paul W., Charles H., George and Ashur Mousel. The girls were Lucille, Ruth and Madeline Mousel.
In the early years of the brothers' partnership, they were active in the show ring promoting their cattle and the Hereford breed. Entries by Mousel Brothers appeared in many of the major shows from 1905 until 1919 and the trophy room at the Nebraska establishment was well hung with ribbons of varied colors. They stood high in the American Royals of 1906 and 1907 and again in 1918, and at the International in 1907, 1908, 1916, 1917, 1918 and 1919. In 1910, Precelia M. 2nd was senior and grand champion female for Mousel Brothers at the National Western Stock Show, in Denver. These early shows helped the brother promote their herd in later years.
These two brothers were truly devoted to livestock promotion and care, especially to the Hereford breed. Many of the top Hereford breeds in the Midwest can trace their lines to some of the Mousel Brothers' cattle.
