There was one Alfred Marcontell listed who lives in Saratoga, TX. Would this be your uncle?
There was one Jean R. Johnson listed who lives in Bullard, TX? Would this be you?
Do you live near a large genealogical library, such as the one in Houston? If so, you can research your Marcantel/Marcontell ancestors in the published records of the Catholic Church in Louisiana. I have been told Houston has a very good genealogical library. I use: Southwest Louisiana Church & Civil Records by Rev. Donald J. Hebert. There are 41 volumes. There are actually 5 books in revised volumes 1 & 2: Volume 1-A (1750-1800) Volume 1-B (1811-1818) Volume 2-A (1801-1810) Volume 2-B (1819-1825) Volume 2-C (1826-1830) The books are in chronological order by year, then alphabetized. Fr. Hebert died this year. We will miss him. To learn more about Fr. Hebert's publications, look at his website:
I also use: Diocese of Baton Rouge Catholic Church Records.
I found Francois Marcantel, sergeant in Mr. Artaud's company (Mathieu of France & Marie Francois) m. 7 May 1754 in St. Francis of Pointe Coupee Catholic Church, Anne Rondot (Jean, dec. & Marie Colon) Volume 1, page 193
Anne Rondot is the sister of Cecile Rondot who married 8 July 1747, in St. Francis of Pointe Coupee Catholic Church, Pierre LeDoux of Boucherville, Canada.
I am descended from Pierre LeDoux and Cecile Rondot. My mother was Alcina LeDoux (1909-2000), d/o Villeneuve Ledoux (1861-1919), s/o Auguste (1826-1902), s/o Auguste (1792-1826), s/o Francois (1755-1812), s/o Pierre LeDoux (1713-1768).
If you can give me a brief line of your Marcantel descent such as I did, I may be able to help you in your research. Because there are so many places to look, give their names, dates, and locations to the best of your ability.
The Diocese of Baton Rouge Catholic Church Records begin with the year 1707 and end with the near 1891. There are 18 volumes.
