Does your LO have a birthmark that matches another relative's?

When DS was born this week we saw he had marks on his forehead and nose like DD. DD had spots in those areas but DS has a more prominent line from forehead, down his nose, almost to his lips. DH and I were joking about what sorts of objects I must have in my uterus.

Shortly after DS was born MIL sent us some pictures of DH where she thinks he looks a lot like DS Whatevs, I tjought, DD was his clone. This kid cannot look more like DH. Then I saw that DH had almost the same line on his face from forehead to nose. It is about 75% as long as DS's and looks like a mirror image (unless the photo is a mirror image). So weird. It gives me hope that DS's markings will fade since DH doesn't have any visible lines now.

I was looking for more information online but have only seen legitite sources mention anecdotes of matching birthmarks. Does anyone else have one or have a LO that inherited them?
