Hi! I have their marriage certificate and wedding photo, and have grown up knowing the children of their children. Oh my goodness! I'm the great-granddaughter of Rose, and my name is also Rose, and I could almost cry, I am so happy to see this. My e-mail address is rcdrakewrites at gmail. Send a message if you'd like to exchange information.
Do you have their marriage certificate? I have the crispy old original with cursive in fading ink, but Barbara's name on it looks like Becola to me. It says they were married in Northumberland County on February 5th, 1906, license number 14409.
But, the children's names and death years match the children of my ancestors John and Barbara exactly; it has to be the same people.
Sorry to be vague. I am just gathering this information and largely relying on the stories of their grandchildren.
