I appreciate the text files and the GEDCOM you have generously shared with the Rivard GENFORUM. Can you identify the source of your GEDCOM? Perhaps you've incorporated content gathered by Ross Vinson (Red Oak website) and/or Mary Ann Mickey (Rivard website)?
I'm interested in proving the family of "Joseph Revoir" [Joseph Revard] of Kansas City, Jackson Co, MO. In the 1840 US Census (p60), the "Joseph Revoir" household included Joseph (head), a female of same age, and 5 children under age 15.
Ursula Rivard is my research interest. However, as you can see, this 1840 household does not include a female born "1833" as shown on the GEDCOM file. If this is the correct family, then Ursula is younger (possibly the female born 1836-1840?) and Mary Ann was born after the 1840 Census date, or vice versa.
I am a gr-gr-granddaughter of Churchill A. Fulton, aka "Church" and "C.A." and, through the records of the Osage Nation and research of Nick Wangenheim of Auburn, CA, I can prove that my ancestor Churchill A. Fulton is "Church Abner Fulton" who fathered a daughter by Ursula Revard.
The Fultons were merchants/traders on the Missouri River with business interests at Kaskaskia, present Randolph Co, IL, site of the large William Morrison and Pierre Menard trading houses. Kaskaskia, now washed away, was situated on the east side of the Mississippi River, south of Cahokia. The Fultons operated a ferry across the Mississippi and sold livestock to the William Morrison store.
During the American Revolution, George Rogers Clark and a group of Virginians (including Samuel Fulton), captured Kaskaskia from the British. After the War, Clark and Fulton were involved in several business ventures and Samuel Fulton traveled to Paris on behalf of Clark.
I'm hopeful that you and I can add more to the Fulton, Roy, and Revard family histories.
