I just checked my St. Alphonse Cemetery & Burials book and I see that there are burials for several Laronde's including:
Adeline Laronde who died 14 Dec 1851 at 9 months daughter of Alexander Laronde & Mary Ann Stokna. Also registered at St. Columbkille.
On the Stoqua/Stokwa side of things there are burials for Alexander Stokwa s/o John & Mary Ann 1847;
Louis s/o John & Mary Agatha in 1851;
Mathew s/o Mathew & Mary Eliza in 1876.
Margaret Stokawa d/o Amable & Margaret Bernard in 1875;
Mary Elizabeth d/o Peter Bernard Stokwa & Mary Eliza in 1880
I can't tell you about the baptisms or marriages so I suggest you review the microfilmed registers of both St. Alphonse and St. Columbkille as the missionary may have recorded the events in both parishes.
