the original family name was glazer( the meaning :a glaser, fixing windows etc. after comming to Israel and in the process of trying to be being fully ontefrated( in addition to the wish of Israels' founder David Ben Guruion, that Israelis change the surnames in to hebrew ) i thought first of splitting the name: gal -zer and gave up the zer and in the gal changed the a into I and became GILL. today I wouldn'r have done it.
Old English from older Danish: means slit, rift, rill. Think 'fish gill'. Old English: Jack and his Gill went up the hill. -- Jock Gill
