I am assuming you are asking if a John Remington is a surety baron descendant, or perhaps a Gateway Ancestor? John Remington is not documented as being one of the 240 or so known MC Gateway Ancestors by Douglas Richardson. This does not mean that he is not a surety baron descendant. There is not enough information in your post regarding the lineage of John Remington to make a preliminary assessment. There are many thousands of Individuals who may be lineal descendants of one or more surety barons that simply have not yet been documented or proved as such. More information in regards to his lineage or a Wikitree profile ID, if he is on Wikitree, would be helpful. Is he currently listed in your family tree ?
