This cemetery was established in Cedar Hill, Texas in 1848. When the 12-year-old son of a pioneer family, Jacob and Drucilla Boystun was kicked in the head by a horse and died. The boy was buried on their private land under an old oak tree. Jacob, James Holland and M.A. Davis, along with some others cleared the land for the cemetery.

Jacob Boystun deeded three and a half acres on what is now Texas Plume Road to Mr. W. S. Ricketts, Robert Grounds and James Holland who were the trustees for the Christian church school on August 1, 1879. A.T. Baggett sold an additional one and a half acres for $75.00 to the trustees in 1907.

The date is uncertain when the very first church/school was built. It is known to be before the turn of the century. The first building which was on the west end of the present-day cemetery burned down. A second church/school was built just east of the old church. Gladys Thompson Potter was the last teacher at the school before the students were moved into the larger school in Cedar Hill in 1933.

The cemetery dates back to the days of cedar wood coffins and horse drawn hearses. Addison Hendricks was a coffin builder in the early days of Cedar Hill. He built coffins from hand cut cedar logs and finished the inside of the boxes with domestic fabric and fine velvet that was purchased from a peddler that frequented the area on his route.

In the spring of 1848, a wagon train came to Texas from Illinois. Some of the families on this train were Jacob Boystun, Isaac Lowe, Robert Ground, James Holland and their families. It was a six-week journey if the weather was good. The families settled 20 miles southwest of Dallas on Mountain Creek, and Jacob built his home there. Jacob G. Boystun married Drusilla Ground on August 27, 1833 in Abington, Illinois. When they arrived in Texas, they had five children and two more were born in Cedar Hill. In 1850 Boystun was issued a certificate for 640 acres in Dallas County by the Peters Colony Emigration Company. Boystun is listed on the 1850 census showing a family with five children. Jacob and Drucilla built a home on their land that stood for 72 years. It burned down in 1920.

The Pleasant Valley Cemetery is located within the city limits of Cedar Hill, Texas on the southwest side. It is located about a half mile west of highway 67 on Mt. Lebanon Road and then about one half mile west on Texas Plume Road.

Because of the very limited space, new burials are limited to descendants only. Many of the relatives of these early pioneers still remain in the Cedar Hill area.

The Pleasant Valley Association installed a wrought iron fence with a large gate for the entrance in December of 1972. The association maintains the cemetery.

In May of 1995, the cemetery was dedicated and received a Texas State Historical Maker.
