FOR centuries, she was thought to have been the only female on board the Mary Rose.
Hatch was lost with the crew of the flagship 500 years ago in the Solent off Portsmouth.
Divers discovered the animal’s remains near the carpenter’s cabin. But now, DNA experts have discovered Hatch is, in fact, a male and could have been a jack russell-type dog.
Hatch’s remains are on display at the Mary Rose Museum, along with thousands of other artefacts from Henry VIII’s ship.
Maritime archaeologist Alex Hildred said: ‘Genomic DNA extraction is something that we have only recently been able to use in amplifying ancient DNA.
‘It can give us the sex, colourings, coat and regressive genes, and confirm that Hatch is in fact a boy dog.’
The testing was carried out by dental students at King’s College, who analysed information taken from one of the dog’s teeth.
Hatch was on board the Mary Rose as a rat-catcher as sailors believed cats brought bad luck.
