Otto came to the Thirteen Colonies as a young man, arriving aboard the ship Edinburgh on October 2, 1753, his age given as 20 years.
[1] He married Anna Catharine Dauterich; their children were born in Lancaster and Montgomery Counties in Pennsylvania.
By 1784 he was having baptismal certificates printed at the press of the Ephrata Cloister; the woodblocks used to decorate the pieces may have been designed by him as well.
Some of them contain longer certificates which appear to justify infant baptism, a practice generally disdained by Mennonites in the area.
Otto also created broadsides featuring Adam and Eve during his career, as well as spiritual mazes, bookplates, and presentation pieces.
