looking for the name of a book I read around 12 years ago?

I asked on here before but didn't get any reply's.The book tells two story that are intertwined.The part that is in the past is about a girl who I think was a gypsy.For some reason she goes to stay with a family who may have been British or Irish or something along those lines. I remember there was a part where she has her period and the son was around her and something about her people not letting the girls on there period around the men ,something about it cursing or tainting them.Her and the son fall for each other and sleep together and she gets pregnant.When she goes back to her people and they find she been with some ,and she already betrothed to someone, the plan to kill her.

The guy she was with I think kills or takes the blame for the death of the person the girl is betrothed to and goes to jail.her people curse her and her descendents.She goes back to the family and has her baby I think it was a boy.she also has a cat that never had a litter till she got pregnant.I think the girl disappears after having the baby and come back with the cat sometime later.

then the part that takes place in the present is about her descendents.there was a woman and two guys.I'm less clear about what that part is about.what i can remember is something about the guys mother i think left when they wore young and she had the girl.ether they found her or she found them and the guys start falling for her and she starts falling for one of them.I think the one she falls for ain't really her brother he had a different mother then his brother but didn't know or something. but the falling for the sibling is suppose to be the curse.I think the name had eyes in the title,something like gypsy eyes or cat eyes ,I've tried looking for those names but can't find anything like what i'm looking for.I thought it may have been a V.C. Andrews story but i looked and none of them sound like this. does anyone know the name of this book?
