I'm assuming these two people are siblings maybe even twins..as their names appear on a stained glass window in a church built in 1893 and incorporated in 1897 in Henryville, PA..the dedication reads

In Memorium
Ada O Nash ~~ Jay M Nash
By Their Loving Mother

but no dates…I found a lot of Nash families in the area of both Monroe, Co, PA and Luzerne, Co, PA but cannot find any info on Ada and Jay Nash..also checked LDS and Ancestry trees..for births or deaths anywhere..its like they didn't exist which makes me wonder if they died at birth..but I would think that there would still be a record...any ideas?
