The brother to Robert and William is Lorenzo Streeter, he is on the same page as William in the 1900 census, he is married to Olive Streeter in 1900.
I knew there was a connection to George and Sarah J. Yerdon, they seemed to be showing up everywhere I looked, i just didn't look into it to make the connection - so I thank you for that information.
It does indeed sound like you found Nicholas, I am going to see if i can make that connection with Nicholas in Hammond to the Nicholas that was chopping tree's. If you want, I can let you know what I find out.
Thank you for your help, I'll be in touch.
Hope the streeter info helps you, let me know if you need any more info about them.
