Charles Evans's wife Anna's father was supposedly an Admiral Robertson or Robinson (unsourced family notes), who was lost at sea around the time his other daughter Lib was born. A family letter says Lib said she never knew him because he died at sea. Anna was born in about 1829, so his death would have occurred sometime after that but I don't have records for Lib so I'm not sure how much later. According to census records, Anna was born in Pennsylvania, so he presumably lived there at some point in his life. Can anyone help me find him and his family? I've had no luck so far.
Because I'm not certain of the surname I haven't made a profile for Anna yet and I'm linking here to Charles's profile, which has info on them and their children. Charles and Anna's oldest son is named Robertson Evans (or maybe John Robertson Evans), so that seems more likely to be Anna's surname, but sources are needed. Thanks for any help!
