I have extensive data on Jonathan Dan and his descendants. He is my 4G-grandfather. Note that he spelled his name with one "n". His children and grandchildren did not add the second "n" until the mid-1800s. His son, Philip (one "l"), and wife, Rhoda, had 5 children: Rachel, Isaac, Phebe, Ebbert, and Minerva. Minerva was definitely a Dan! The confusion about the name "Brown" may be due to that being the maiden name of Philip's mother, Mary Brown Dan. We don't have middle names for Philip's children, but perhaps Brown was used as a middle name for Minerva. Could you tell me how you know that Phebe was born in PA? We thought he moved there closer to 1815, but we lack good info on it. You may know that Philip moved to Broome County, NY around 1850, founding the hamlet of Danville. I have more details on Minerva if you contact me at firstname.lastname@example.org.
