That is a tough one Andrea.
I know in my arena I have offered to help people and have come to dead ends. I always say that I will do what I can but do not put in a guarantee. Research sometimes takes years and years to even find one person. Thirty days is not a long time in my opinion but if you are concerned, give them a call and ask how they are coming along.

I am sending you good vibes with hopes you will get the answers you seek
