Hi Gloria,
I am not sure if I can help or not, but maybe we can help each other. Like you, the Leach trail in my family goes cold very quick. My grandfather was William Albert Leach, his father was George Albert Leach and his father was William Leach. Based on what I have, William Leach born in 1835 in Illinois, but I think that is sketchy. I am 99% sure that parents I have for him in my tree are wrong, I found something and put them there as a place holder. In 1858, he married Anna Bell in Marion, Indiana. Anna Bell was born in Marion, Indiana in 1839. What I don't know is how my Great Great Grandfather ended up in Marion, Indiana and how many siblings he had. I do know that he moved West, but who knows how many Leach's were left in Indiana. I have done DNA and I have not had any matches on my Leach side with the exception of my Mom. I do however have a ton of matches through Anna Bell. So, I know my Leach connection goes back to Marion, Indiana, but I am not sure if we are connected in any way.
