Daniel and Margaret McMullen and their children built this home in 1868 after coming to the Pinellas Peninsula in the early 1850s, leaving during the Civil War, and returning by wagon to the Largo area in late 1865. On their 160-acre homestead they raised livestock and grew crops, sharing the frontier with bears, deer, and turkeys, and bears sometimes raided the nearby pigpens. Built of native pine in the Florida Cracker style, with two formal rooms, two shed rooms, and a dogtrot breezeway, the house was expanded by later generations, and the original homestead well wall still remains. The McMullens lived in the home for 123 years: Daniel lived there for 40 years, and after about 1910 his daughter and her husband lived there and raised some of their nieces and nephews as well as Daniel's granddaughter Nancy McLaughlin, who remained there for more than 80 years until 1992. The family held notable reunions there, including a July 1925 gathering marking the 100th anniversary of Daniel's birth, when 625 descendants of the seven McMullen brothers who settled Pinellas came together, arriving in more than 100 automobiles for a fish fry and remembrance. The McMullens grew cotton, sugar cane, vegetables, and later citrus, and they also raised chickens, hogs, and especially cattle; by 1890 Daniel probably had the biggest ranch on the peninsula, with nearly 1,500 head of cattle. He was also part owner of a Largo mercantile store, the Farmers' Alliance Exchange, and helped establish the Bank of Largo. In 1890 Daniel sent his daughter Nancy to a Largo sawmill for boards for orange crates, where Jim Hardage saw her arrive by horse and buggy; after a 10-year courtship, they married and moved into the home. During the Civil War, brothers James and Daniel served in the Confederate Cow Cavalry, driving livestock from peninsular Florida to supply Confederate troops with meat, tallow, and hides, and on one trip they herded 365 cows at a grazing rate of 8 1/2 miles per day.
