Double weddings

[Kit]

My grandma and her sister had a double wedding. I had one cert but not the other but found a notice in the paper and then found a wedding photo of the 4 of them.

I certainly have one circa 1840. One happy couple (now married) were witnesses to the brother's marriage. I have one cert. for the direct ancestor but both marriages appear in the IGI on the same day.
