Sorry, my understanding was that, to send personal messages, you only had to establish your credentials once on the site by way of three postings, rather than three postings on each topic.
To reiternate, per my previous message to Steve, I have a Word document containing the lecture given by Rev Thomas Twigg Junior in Ardboe in 1872, in which he describes his lineage. I also have a 1928 obituary of his youngest son, Colonel Edward Francis Twigg, who died in 1928.
