I recently found out that my father had a first marriage and he has another daughter. She is older and has her own family in GA (I live in PA). I had no idea she existed and have never met her or her family. Obviously she and my father did not keep in touch. Thanks to Facebook they kinda reconnected, though I do not think they have met up in person. My mother knows about her, but has not been in contact with her, ever. And to complicate things, my mother and father are separated (they are not really friendly with eachother at this point) already making family affairs difficult. I have never met her and I do not forsee a meeting with her before our wedding day.... I feel very uncomfortable inviting her my wedding, she is virtually a complete stranger and knows no one aside from my father, who she hasn't seen in at least 10 years.
Do I invite her and her family?
