This couple were both German natives. I received one response. It was not even from a relative. The age is as of the date of arrival, making Peter born circa 1826. While I'm ecstatic about this information, I need to verify it with original records if possible.
Verification is always necessary in and of itself.
This search was conducted by searching for Peter Biger in Hamilton County, Ohio, in 1850 with the soundex option turned on to locate the most likely alternate spellings of the surname. Another research goal is to obtain the complete census entry for this Peter. If this Peter Bigger is 70 years of age and born in Kentucky, he's not likely my man. Only by getting the actual census entry will I be better equipped to determine if the individual in the 1850 Ohio Census is a likely fit. If he's not, then I should expand my search to adjacent areas and other alternate surname spellings in the census index.
