Birth year is circa. Last name based upon Andreas mentioning Maria’s son as John Schissler in his 1785 will.
In the New Bethel church records it mentions that “Anna Maria Hagenbuch, single” was the sponsor of her brother Henry’s first born John in 1762. To be a sponsor, it is assumed that Maria would have had to have been confirmed. She was confirmed in 1761 per Daniel Schumacher’s records. This means she must have been born shortly before her brother Michael, who we know was born in 1746.
