Half siblings child

Hi,

I've had a match on ancestry that says 1st cousin but on contact she can't be. I think instead that one of her parents may actually be my half sibling. The match is 1033 cm with 30 DNA segments. She is trying to get the raw data.

It means about the 13% shared so would this be right for a half niece?

Thx.

It looks like a 1st cousin the other one you described would be way less and that amount is perfect for 1st cousin

I thought I'd just pop in and update this. It turns out the woman is my half niece. Her dad hasn't tested but he has a genetic eye condition that my children have that only affects 3/100,000 people so the likelihood of him not being our half brother is slim
