Wayne County, Ohio - In 1840, a David Bay was enumerated in Plain Township, Wayne County, Ohio, heading a household of seven, which included a male age 10 to 15 who could be Cyrus, age twelve at the time. Also enumerated was a female age 5 to 10, who could have been the ten year old Mary Bay who would later marry Benjamin Crull in Wayne County in 1847.
Nearly thirty years later, Mary and Benjamin Crull's son Marquis de Lafayette Crull married Cyrus and Lucinda Bay's daughter Lora Arecelia Bay in Henry County, Illinois. Was Mary Bay related to Cyrus Bay, perhaps a sister residing in 1840 in their father David Bay's household in Wayne County, Ohio?
