On the 12th April 1842, Margaret Pelan was sentenced to 7 years' transportation for stealing a shawl in Belfast. She appears on the Convict Muster as Margaret Pealon and arrived in Tasmania on the convict ship Waverley. You can see some of the records of Convict 55620.
Albert D Pelan who lived much of his life in Belfast in the early 20th century, gained notoriety in 1940 for conning a woman from Offaly by suggesting he was a man of means and was looking for a wife. Alas, all he wanted was the woman's money and he was still married!
Another Belfast Pelan, in 1925, was found guilty of conspiracy to murder in Staffordshire, in conjunction with his former landlady .
