I am researching the family of my gg grandmother, Isabella Mathewson. She was born about 1803 and died 1843. She was married to William Semple. They lived in Pettigo, but are buried in Derg Cemetery Parents of Isabella are said to be Gilbert Mathewson and Annie Wylie. Gilbert or Gilly died in 1820. There appears to be an inscription available through Irish Genealogy. Is there anything available online that I could access? Thanks, Virginia
