Orphan

I'm Dave 28 Electrician now married to Jane 26 and have 2 children by her. We married last year, after living together for 5 years and having the children. Recently I decided to have a DNA test with Ancestry.com and had 1 match. It was Jane she is my sister and we were separated after the deaths of our parents. We were 3 and 1 at the time and Jane had tried last last year to find relatives with ancestry and none had shown up. She new she was an orphan, but wasn't told she had a brother. Nor was I told I had a sister, we love each greatly and have decided to stay together and we have had the children tested for any problems and they are clear. Ancestry hadn't updated Janes profile to married as yet and we have now deleted our profiles.
