Modules & VBA :: Combo Box With Colored Groups

I have a series of records that I would like organised into groups.For example everyone with the surname Jones who lives in Wales and is between 18-30 years old.I would like a Combobox that has that group sorting visible in some way, possibly with colours.for Example if i had the records:

First Name Surname Country Age

Dave Jones Wales 24
Bob Jones England 28
Fred Jones Wales 19
Jim Jones Wales 22
Ian Jones England 29
Frank Smith Scotland 32

I would like a Combo box that shows the names Dave , Fred and Jim with a background colour of Red then Bob and Ian with a background colour of white and Frank with a background colour of blue.how I group (maybe you can add spaces between the names Dave , Fred & Jim and bob & Ian).
