I am looking for info on Barbara Boas & Jacob Levan, he was a coppersmith and resided in Kutztown, they had Hester/Esther who married Oliver Bunstine, Elmina & Juliann. Barbara was the daughter of William Boas who was born in Switzerland in 1739 and came to America in 1770, he was a Reverend [with no credentials]for the Reformed Church in Reading, he was married to Susanna Eppler.
I interested in finding info on Jacob Levan and families and Barbara Boas Levan's families.
