History & Origin
Jillaine is a mid-twentieth-century elaboration that takes the breezy short name Jill and gives it the graceful -aine tail of Elaine and Lorraine. Jill is a pet form of Jillian, which is a form of Gillian, the feminine of Julian from the Roman Julius, so beneath the modern surface lies a deep Latin root usually read as 'youthful.' The name is a good example of how families spun fresh forms from familiar pieces.
It never grew common, holding to roughly fifteen girls a year at its best in the mid-nineteen-sixties and fading by the early eighties. A Jillaine from that time would be around retirement age today, and the name reads as an inventive, distinctly of-its-decade twist on Jill rather than a name with older roots of its own.
