Do all of the MacLochlainns of Inishowen alive today descend from the handful of lines traceable beyond 1700?
No. The genealogy narrows at several points because the lines no longer traced have become obscure for want of records rather than extinct for want of children. Most of the MacLochlainns of Inishowen alive today descend from these obscure lines, there are far too many of them around for it to be otherwise.
