It has been a while since I've checked this forum, and I'm sorry no one has apparently replied to your post.
Yes, of course you're a cousin! And this is good, because I have always been unclear as to how the Daniels and everyone fit in exactly. I know my grandparents always send Christmas cards to the Daniels family, but I never had all the details.
You asked about May Hatty; she was my grandpa's sister. E-mail me, and we will work out all the details.
And yes, we still have a big picnic every summer. Want to come?
