I have now actually found another sister on my dad’s side that is about 2.5 yrs younger than me. Again we grew up about 40 miles apart in small towns in East Texas. This just happened - she was his only child and married to her mother. She is in the process of taking a dna test to be 100% sure. If she’s not my sister then she would be a cousin but I know it will be a match. For three yrs I sat on this info and finally reached out a few months ago. She had big emotions. We’ll see what happens.
