Hi Amanda, The surname Getty is a shorten version of the surname Dalgetty, which is from the Pictish race. There are many spelling variations of the Dalgetty name, Getty being on of them. The Getty's and all of the spelling variations of the Dalgetty name are septs of the Clan Hay. The surname Dalgetty is listed under Clan McDuff, but the Dalgetty tartan falls under Clan Hay. If you attend a Highland game in your area be sure and stop at the Clan Hay tent and join. The other origin could possibly be MAG EITIGH which is Irish.
