Just to add to this story -- the two 1907 Sharrock Vincent deaths - firstly, they are cousins, their MCRA being Nicholas Vincent and his wife Jane Woon. Among their many children were a Nicholas, and a Sharrock (the one whose death was 1878, as I posted earlier here). Nicholas the younger married Mary Ann Spry (also as I posted), and they had Sharrock (1849-1907). Sharrock the elder married Ann Rickard, and they had Sharrock (1858-1907).
Now comes something new - 1849 Sharrock and his wife Mary Pearce played host to 1858 Sharrock at their home on Norfolk Road, Falmouth, in 1881, when 1858 Sharrock was an apprentice Pilot (that's boats, not aeroplanes).
So the cousins knew each other. It's interesting that they died the same year.
