if the deceased died without a will and there are no immediate family members surviving the money will transfer to the crown until its claimed there is an unclaimed money register maintained i think by treasury (home office?) if you can locate the register you should be able to search it yourself once you have located the name of the deceased that will verify the email you can then claim your share - the publication of the unclaimed money register is usually the trigger for the correspondence from the middle men if they are writing to you it has to be commercially viable for them so its probably worth checking into

as a guide have a look at the victorian treasury unclaimed monies register and the claim forms - you will need to prove a blood
relationship

on the other hand if there is a will you can do a probate search through the probate courts however if you are being contacted by an agent it suggests she died with out a will
