Hello! Just found this book thru Google books:
http://www.worldcat.org/wcpa/oclc/01611152
Full title seems to be:
The life, adventures, and unparalleled sufferings of Andrew Oehler, containing an account of his travels through France, Italy, the East and West Indies, and part of the United STates; his imprisonment in France, Germany and Spain: and the latitude, soil, climate, productions, manners and customs of the different countries.

Anybody know this guy's lineage?

Thanks!
Ellen Oehler Blackstone
