Before Collin County was formed, Sam Young, a pioneer from Illinois, bought land in the Jacob Baccus survey in 1845 and established Young Cemetery in 1847 when his first wife, Patience Cornell Young, died. Her grave, dated February 17, 1847, is the oldest marked grave in the cemetery and the second earliest known marked grave in Plano by one month. The cemetery covers an acre of land near Young Branch. The last acreage of the farm was sold around 1972, but Sam Young's granddaughter Gladys remained, living in her father John Young's house until shortly before her death in 1998. The house, built by John Young, was moved in September 2001 to the Heritage Farmstead Museum in Plano, where it was restored and displays some Young family artifacts, including family Bibles. The Young Family Cemetery Association was formed to preserve and protect the monuments and grounds. Families represented in the cemetery include Abbott, Baccus, Bankston, Crenshaw, Dennard, Finley, Jackson, McConnell, McQuerry, Teel, and Young. Some monuments are hand engraved, while others are highly ornamented, including the Woodmen of the World monument for Adam Teel near the original entrance. The gate posts still stand, but the gate was removed and is kept at the Heritage Farmstead. Some of the Young family traveled west to Montague County, and some are buried in Rowlett Creek Cemetery, including Gladys and her mother; Rowlett Creek Baptist Church once stood on that ground. Veterans buried in Young Cemetery include Jacob Baccus, Jacob Houts, and Thomas Finley. Finley fought in the War of 1812 and has the earliest birth date, 1790; his grave includes two headstones and a special marker for his service. Young Cemetery was recognized by the Texas Historical Commission with the Historic Texas Cemetery designation for the contributions of those buried there during the early settlement of Collin County.
