I have Teagan as my middle name and is spelt 'TEA' even though funnily enough I HATE TEA. I have never seen it spelt like this before. I was surprised when I saw it spelt like this!
I think this name looks better Teegan rather than Taegan. This name is ok, but it is not something I'd name my daughter. I neither like it nor hate it.
