Thanks Frances. Hope you didn't think I was critical of Brian Lawson's work, which continues to be so helpful to those of us who live nowhere near the IOM. Mistakes are easily made in copying exercises, so I was just wondering if there could be an error to account for Catherine Callow's burial date really being 1910, as the other evidence we have suggests she died after my grandfather George arrived in Australia in December 1909. Unless I've missed something, the only other Catherine Callow buried in Andreas after the '1901' entry looks like one in 1952, which I'm pretty sure is Catherine's granddaughter Catherine Jane Callow dau of John William (1873-1912) & Mary Ann nee Kneen (1873-1903).
Thanks again for the clarification
