A grave marker for John H. Blackshear, July, 1836 – January, 1868, can be found in the Pillot Cemetery located south of Tomball, some distance off Holderrieth Road. John’s son was William N. Blackshear. It has been reported that William and his wife Elizabeth came from Trinity County, Texas in 1862 to the Willow Creek area. William Blackshear bought land on Spring-Cypress Road around 1880. He ran a store and became Klein’s first postmaster on September 8, 1884. This store, located east of Adam and Friederika’s farm, was part of a long, straight building with a little porch and easy to find in a big bend of Spring-Cypress Road. There were about 250 people served by the post office located about halfway between the post offices at Spring and Kohrville. Mail was delivered three times a week, on Tuesday, Thursday, and Saturday. In 1902, William Blackshear and his wife Elizabeth sold the store and land to their son-in-law, Charles Klein, the youngest son of Adam Klein. The Klein Post Office stayed in operation until September 15, 1906, when the post office was closed and mail delivery was transferred to the Spring Post Office.
