The surname Marrow was originally spelled Marow. Before that it was Marewe. This dates back to the year 1245 I believe. It is French in origin. Now, remember, France was once part of the Roman Empire. Soooooo you can figure the rest out. Anyone ever heard of G6PD? Anyway, I'llprovide everyone with my passenger ship registries for Marrows later. It gives the name, date,city/port of call, State, ship and where you can find the same info and the page number!
