I know its been a while since you wrote your original message but I just got to Genealogy.com.
I too am a descendent of John and Harriet Durst but its through Horatio Durst, Charles Placido Bruno Durst brother.
I have a copy of Frontier Times if you still need it.
It is nice to hear someone else had visited the Durst family cemetery.I have not been there in a while but have visited it many, many times.My grandmother grew up on that property.It is also nice to hear someone has set up an account for donations.
If you would like to exchange information on the Durst family, please contact me.
