Carolyn; I found an Elias Pennington born 1795 in Md who was living in 1850 in Little Britain Township, Lancaster County Pa (just north of Rising Sun MD) who married a Jane Grubb and sold land to John Benedict Pennington, married to Ann Mercer, in/Abt 1860, the year both of them died. Elias is Buried in the Little Britain Presbyterian Church Cemetery. Could he be your Harford County Elias? John Orr Pennington
