Crown Prince Louis, fleeing the French Revolution, took up the Paiesieur name to conceal his identity long enough to get him to England (where he was protected by the King) and then to America, after he acquired holdings in the Virginia Company. Once in America, he adopted Payseur as his name.
Paymaster in French is maître payeur. Sometimes caissier which is the root of the English 'cashier'.
Paiesieur makes no sense unless it is a corruption of paie seur which means 'payor'. That would make sense as a pseudonym (pseudonyme).
