Thank you Wendy. This had me frustrated for quite some time. I've had bad experiences going on private property and the curator at the museum in Brownsville said not to go without permission. But eventually, via a photo request on findagrave, I got the pictures and permission to go myself. I have so far only had a chance for a brief visit. On my visit there was an elderly man asleep in a chair beside the gate. I guess he is the property owner and I still felt propelled to get his permission. He seemed very annoyed that I woke him but had no problem with us visiting the cemetery.
