Do you know Florence's maiden name, parish or names of any offspring?
Brian Lawson has a July 2 1905 marriage in Douglas between Robert James Corlett and Annie Florence Kermode. A little early. if your age for Robert is correct.
However one Robert Corlett that I found in the 1901 census was 27 and living at Eary Jory in Malew RG13/5803 folio 8 page 7. He is the son of John & Jane Corlett. Annie F Kermode 16 is a servant in the same house and there is also a Kermode Kamily on the same page. That would make his date of birth c. 1874. There is a Robeth James Corlett buried in Marown on March 12 1958 age 84.
