I hope you don't mind me contacting you like this. My name is Jofeb04 and I am trying to find my birth mother (or just her name would probably be safer) I was wondering whether you might be her relation?
If not then I apologise for contacting you. If you are, I would be very grateful if you could let her know Jofeb04 would love to talk to her.
You could ask that easily enough. You could always be an old schoolfriend or something
Although that could look dodgy if he says 'yes' then you turn round and say well actually I might be her daughter..
Have you got any other way of contacting her? What about googling her name and seeing if you can find out where she works or something. Do you think she wants to be contacted? Do you know the circumstances behind why you were separated?
