Meaning & History
Perhaps from a hypothetic Germanic name like *Ismegi or *Ismagi, *Ismagin, which would mean "iron strength" from isan, itself from îsarn "iron" (see Isanbrand; however, the first element could also be îs "ice") combined with magan "strength, might". Isemay was first recorded in England around the 13th century.
