I had some disturbing mail through the door the other day. It was addressed to me from an anonymous person. I was about to throw it in the bin when I saw that it was addressed to Beastly Gerbil, not my real name so I realised it was a puzzle. It started off like this:
Someone is in danger, and you need to warn them. I can't say directly who in case this is intercepted so I have hidden it as a puzzle. Work this out and warn the person.
On the back was this:
23rd July 4516 - CEDFCED - If you do in fool's rain down
23rd April 7615 - DDAGAAF -Your condition that now slows a lie

26th May 1734 - FFAGFDE - Is walking boots filling know suppose newts
Who do I warn?
@Levieux is on the final step. Now you just need to look at the steganography tag. You are looking for a type of relative.
