I've met an Ishbel ... though I prefer Elspeth. Known some good people with that name.
In Glasgow, have met several older ladies named May, Betty, Anne/Annie, Katie/Catriona, Marion, Fiona, Alison (rather pretty, I think), Janet/Jennet rather than Jeanie, Helena, Margaret/Maggie, gazillions of Isobel....
Men and boys - Andrew/Andra, William/Billy/Wullie, Michael (popular in Catholic circles), Walter (am not sure why), Jim/Jimmy (Jamie is Edinburgh, nuff said), Ian, Allan, Alasdair, Archie, Malcolm, Lachie and, as previous poster said, Scott, Ross, Craig etc plus a middle class Maxwell and Hector. Modern popular names include Lewis, Harris, Fraser, Cameron, Innes, Finlay...
