I'll post more later, but some recent research suggests that Charles LaPorte was also Charles LaPorte-Denis or simply Charles Denis, who married Marie Guenet. We've had marriage records for Charles LaPorte and Marie Guenet for some time, showing their parents names. What was missing was a connection (other than the 1850 Census record) between Jules and Charles, since that record only put them as next-door neighbors, living in a home of a man who might be his brother.
Cousin Jonathan found a second marriage reference that included the "Denis" name, which got us searching for other possibilities.
This morning, he emailed me the following message:
(Searching for Julien Denis, Laporte, or Denys), I found two baptisma lrecords of interest on ancestry.com : 1) Julien Denis, who was a sonof Charles Denis & Marie Guenet, born/baptized in Jan. 1810, in L'acadie. 2) Julien Denis, also a son of Charles & Marie, born & baptized Apr. 22, 1815 in L'acadie (as a side note, interestingly, this entry is right next to the baptism of a direct ancestor of my brother-in-law - Zoe Campbell).
I did not find that either of these Juliens died. It could be possible that these 2 boys may be your Julius & Julien. The French version of both of these names is Julien.I went to the LDS site, www.familysearch.org and started to browse to the records for the St. Marguerite de Blairfindie church in L'Acadie, Quebec. This is where Charles and Marie were married. It took some time to zero in on April 22, 1815, but this is what I saw as well:
My French is rather horrible, but I can make out: "Le vingt-deux avril mil huit cent quinze" which is 22 April, 1815.
Also, "batisme de Julien ne aujorud'hui du legitime marriage de Charles denis . . . et le Marie Guenet . . ." which is "baptism of Julien, born today of the legitimate marriage of Charles Denis and Marie Guenet."
Julius, based on my research has shown birth dates anywhere from about 1813 to 1820. For example, in 1850 Census, he is listed as born about 1815. In 1870, it is about 1819. In the 1880 Census he is listed as 68, suggesting a birth date in 1812.
In his Civil War Pension claim, he has identified at least at one place, a birthdate of April 4, 1812. My recollection is that was in his disability pension. In his widow's pension file, there is a marriage record (second hand transcription from the then-current minister of the church in which he was married), which suggests he was 58 years old in 1878 when he married Louisa Bartlett. That would put his birthday about 1819 or 1820.
So this is certainly not INCONSISTENT with those.
Next is to find the same record that Jonathan mentions for the "other" Julien, which would proabably be the man known in Clinton County, New York as "Julian." Maybe also a hunt for Francis Nelson, who might also be Francois Narcisse. Perhaps even a Jospeph, who was rumored to have existed as a third or fourth brother.
Also, I need to track down the original of Julius's death record perhaps both from the State of New York and also from St. Anne's in Mooers. The collection of records for Julius's death indicates "Charles" and "Marie Gosset" as the parents. We're speculating that this is poor transcription of the handwriting for "Guenet" but it would be nice to see the original.
