Congratulation, Carl, on receiving your Regular Member's certificate. I am surprised that you are the first Stymiest to do so. One would think that the Tabusintac families would be rife with members. Of course, there are difficulties. Duncan Robertson, as a regular with the 42nd, might not be considered a Loyalist in the strict sense. Because of the difficulty of proving John Murray to be the son of John Murray of North Bedeque, PEI, that line might be hard to prove. I have never attempted it, getting my certificate through my mother's family. The Hierlihys shouldn't have much problem. Neither should the Prices.
I suppose with Charlotte Taylor, the Andersons, Loggies, etc. probably being pre-Loyalists (although not in the Maugerville sense) there would be problems. At least for the Stymiests, you have laid that all-important ground work that should make any other of Benjamin's descendants applications relatively easy.
