John Baptiste Chaison was born August 7, 1745 in Nova Scotia, but migrated to France when his country was ceded to England. He returned to America when the American Revolution broke out and served with Colonel Benedict Arnold at the Siege of Quebec and with General Lafayette at Brandywine. He was wounded at the Battle of Eutaw Springs, but recovered to fight with General Lafayette at Yorktown. In 1832 he migrated to Jefferson County, Texas, where he died on July 20, 1854. He is buried in the Jirou Cemetery located north of Beaumont, Texas. The cemetery was abandoned when the freeway was built, and a church was built over the site of his grave. A DAR grave marker was placed on his grave site in 1944, but the marker was moved to Pipkin Park in 1969 on the west bank of the Neches River near downtown Beaumont when the church was built on the grave site. In 1976 the Texas Historical Society placed a marker in Pipkin Park and a SAR marker has been placed as well. Source
Note: In 1969, Jirou Cemetery, the city's oldest burial ground, was razed in order to build the church shown below. None of the graves were exhumed and witnesses reported that the tombstones were simply thrown out into the street. Fortunately, Jean Chaison's 1940s-era grave marker was recovered by members of the DAR and placed in nearby Pipkin Park. Jean Chaison's remains, however, as well as all of those others buried in Jirou Cemetery, still lie here. The GPS coordinates will take you to the position seen in the photo below.
