David, there were many Sarah Bloomfields but most of them who were born in the US before 1800 were born in or near Woodbridge, Middlesex Co. NJ. Some Bloomfields had gone to KY, NC, OH by that time. Since Sarah married in MI, I suspect she was from one of the OH or KY families. You might start your search in NJ, then branch out. There are many other researchers who have websites and some of those may show the right Sarah. Some Bloomfields were in Burlington, and other nearby NJ towns. Also I noted that the middle initial shown on www.familysearch.org is different than what you listed. The marriage records were from an extracted source so it could be a transcription error. I will look through my Bloomfield records to see which males had daughters named Sarah. If I find any in the 1835 birth year, I will contact you.
