Earl, I cannot answer your question definitively, but I actually have a theory on which Henry Yerger might have married Catharina Gilbert.
My 4G GF was Henry Yerger born in 1775 son of Michael of Colebrookdale (attended New Hanover).My Henry died in what became Snyder Co, PA in 1852.His wife buried with him was Maria, maiden name unknown.Maria was born in 1785 -- 10 years after Henry -- and they married in about 1803.
I am well aware of the tombstone of Catharina Gilbert and have theorized that possibly my Henry married first Catharina -- because the timing fits so nicely with what I know about my Henry -- he was old enough to have married in 1798 and what I know about what would then be his second marriage it was not long after Catharina died.I have even theorized also that maybe Maria was Catharina's sister since often a man married a woman's younger sister in those days when his first wife died quite young.
Obviously, I'm just guessing but I think it is a reasonable theory to pursue further.
