My mother is an out of wedlock (born to two single parents) child of an American serviceman (WWII). Though formal contact was never made between her and her father, he was aware of her birth. She was able to meet with her paternal grandparents back in 1978 at which her paternal grandmother acknowledged her. Her father married approx. 2 years after her birth and had three children (one now deceased). Our attempts at contact has repeatedly been rebuffed. We have just found out that her father passed last June 2014 and that a notice of trust was filed with the Florida Palm Beach County of Clerk on January 2015. What are her rights, if any? Any information and/or direction would be greatly appreciated.
