At findagrave.com, there's a listing for Electa Wood (1789-1868) buried just across the southern border of Waushara County at Bush Cemetery, Berlin (Green Lake County). Is this the same person?
She's listed as the "wife of Frederic [sic]" and there's a Frederick buried there, too, but with no birth and death dates. From your query and other information posted on Ancestry.com, I see that she had a son with that name, as well, but a quick review of that information seems to point to other burial places for both her husband AND her son.
She appears to be buried near one of her daughters, Sarah (Wood) McNely, who also shows up in those other family trees on Ancestry.com.
Based on the info in your query, I couldn't tell if this is "new" information for you, but wanted to mention it just in case.
