In the book, Geographical Place Names of Prince Edward Island, by Alan Rayburn, he describes the community of MacDougall - 5 mi S of Tyne Valley in Lot 15. Post Office 1876-1914, James MacDoughall first postmaster. Meacham 1880 shows Jonathon, Jas., and Rodk. McDougall at the corenr, and Danl. and Neil McDougall nearby. The school in Meacham 1880 is Cross River (former school district of MacDougall).
On the northwest corner of Routes 12 and 167 in MacDougall is this property - the house appears to be unoccupied.
A little further up the road on Route 12 and at the corner of Baker Road is the farmstead below. On Meacham's 1880 Atlas it shows a MacDonald family living here. The house appears to be occupied, however, the barns and outbuildings seem to be in decline.
