Whoever thought this little congregation would make the New York Daily News?
They did locate the Texas descendant after the article was posted. She doesn't like to travel in winter, so she's planning to come to Michigan in the spring and they will give her the letter in a special ceremony.
They also spoke to some relatives in New Mexico and here in Michigan, but I believe the other ones were distant cousins. The Texas woman is a direct descendant and the letter will go to her.
Apparently two of the three are quite interested in art. Interesting.
