I find a John W. Linthicum married a Diana Causey in Guilford County (Greensboro) NC in March of 1823. They had kids and I think their family is represented by the John Linthicum (some liberties with spelling) in the 1830 and 1840 Guilford County, NC censuses. Diana died in 1842. John died in 1847. Obits in Greensboro Patriot. I'm looking for offspring especially a William.
