Yes, they were two sisters marrying two brothers. That's what made me think that the marriages might have been on the same day!
As you can see, the grooms' parents -Benjamin and Zillah - were witnesses both times.
Here's another challenge: Any sign of (a) a marriage for Edwin Augustus ROSSITER probably in 1890; (b) the birth of a daughter named Frances soon afterwards; (c) the death of his wife some time prior to 1915; and (d) the death of Edwin, probably in 1939?
I have just discovered that he enlisted in the First AIF (Remount Regiment, 1st Squadron) in 1915, claiming to be 50. In fact, he was just a few months off sixty!!
As always, your help would be much appreciated.
Many thanks in anticipation.
Kind regards
Phil
