From what I can tell 7 distinct Lindsay tartans (in all the variations) plus the sept tartan (Birse,which I've only seen computer rendering)........ but wait there's more; Stewart from a maternal g-grandfather, Cameron from another maternal G-grandfather, Gordon from a maternal G-grandmother and Counties Cork and Mead (sp?). Oh my head hurts from thinking about them all...Hamish be afraid, when I'm at your state in life I could have a closet bursting with family tartens.... All wanting to pick fights with each other for hanger space!
