I need a little help deciphering a document. There are two characters that I'm unsure about, and I would appreciate your expertise. The first one seems to be 鵬, with the 朋 written together, but I'm not entirely certain. The second character is a bit trickier. I've searched through several dictionaries, but I couldn't find an exact match. The closest I found was 逆 or 溯.
If any of you have any insights or suggestions, I would be grateful for your assistance. Thank you in advance for your help!
They are both from this page, from a local gazetteer:
