The township contains five cemeteries: Alvarado, Amish, Metz, Mount Pleasant, and Bethel.
The first land registration was made by John Douglas on October 11, 1835, but Robert Jackman and family were the first to settle in the township, in 1836. The 1840 census shows only 16 families, including those of Douglas and Jackman.
Much of this early community was centered on what came to be the village of Richland Center, where a log cabin schoolhouse as well as a Methodist church were built in 1850. When this village, which was never incorporated, organized a U. S. post office, there was already an Indiana post office named "Richland Center", so this post office was named "Alvardo", which eventually became the name for the village. Like the rest of Richland township, Alvarado slowly lost population during the 20th century and, in the 21st century, is a small collection of dwellings, farm buildings, and the Alvarado United Methodist Church.
