Ok
The book about Schaller is Soldiering for glory? Right?
For my informations (1860 US Census and polish sources) Oladowski was born in 1798, Sulakowski in 1827, in Tochman case were many differencies (Library of Congress catalog - 1797, US Census - 1805; polish sources 1791,1795, 1797 and even 1813. I think that real are maybe 1797 or 1805.
I don't think so that Sulakowski and Sulkowski is the one family. In Poland there are two other families.
