Thanks, Kate. That's much appreciated. You may very well be right that the death of Charlotte Elizabeth / Charlotte (baby) is in fact the Elizabeth mentioned on John's death cert. Though not the informant, the wife Charlotte was living at the time of his death, so you would imagine the names under Issue were correct (but mistakes do happen). That just leaves Jane Derbyshire and the fate of Martha. I'm finding a LOT of typos and mistakes in Ancestry info. I used to own all the Digger and Pioneer CDs and found them much better and more reliable. I was surprised to see that there is no historical index online for Tasmania BDMs. I was hoping to check for a death of Thomas Derbyshire c1842. It would be nice if the different states and territories standardised access to the historical records. Oh well. Good luck with the horses! regards, Martin
