Regan/Manley Dairy Farm - Location for Visit

I believe that my O'Regan/Regan line comes from the dairy farmers said to be of Dunbulloge, Carrignavar, Cork. Family lore and AI research are aligning, with a handful of guiding documents that have some holes in the evidence. I'd like to visit in 2027 (either Spring or Fall) and see the land, as well as meet any (willing) living relatives to learn more about my Irish roots. John Regan and Mary Keefe were my 5th great grandparents. Their son Michael Regan, b. ~1829 is my immigrant to the USA and his wife was Sarah Ann Flynn of New Market, Cork. His brother Denis Regan married Norah Murphy. It appears that they may have remained in Ireland. AI provided a list of 10 children in that family, but with no source for the record. Denis's marriage record is the source for the potential location, and a Griffith's Evaluation that appears to match. His daughter, MaryEllen Regan was baptised at Glanmire, per a copy of that record, and a letter from the Catholic Parish at Watergrasshill confirmed Michael Regan's Baptism/Birth date, a copy of which was provided to me by a distant DNA relative. The story is that they were one of the largest dairy farmers in Cork, and when a female heir inherited the farm, it was known for her husband's surname, Manley. It is said to have been sold in the 1990s, I believe, and possibly to the local municipality. ?? I have been searching for decades, and in honor of my father (who has passed) and his passion and pride for being Irish, despite little information regarding his roots, I am eager to create the family album of my visit to the Regan origins, to pass on his heritage passion, clearly instilled in him by his ever-adored grandparents. Any resources and assistance of any kind would be most sincerely appreciated. I'll attach a few reocrds that are currently at my fingertips, including a baptism record that I believe must be Michael Regan's sister. Warmest regards, Colleen (nee Regan).
