JR, I know just what you are saying. I have always had freckles all over for as long as I can remember. I get more in the summer, but they don't go away at all. I joke that for me a tan is just my freckles getting together.
I do have a mole or two, but nothing to speak of. As to the Irish side of the equation, I also have the Hazel eyes to go with the freckles. I teased my youngest daughter that she got her freckles on her nose becasue I kissed her there, and she passed it on to her youngest son. Both of them have only a spray of freckles across their nose and cheeks.
None of my siblings have freckles by the way. Their complexions are a bit darker than mine, so they just tan but have never freckled.
