Hello, new here and hoping someone might be able to help.

I'm having a hard time finding more info on one family line.
I'm trying to find out more about my gg grandparents Frederic (Fred) Robichaud and Elizabeth Gallant(Gallian). Not having to much luck on this side. Their children were born in Chatham, New Brunswick.
Names are Joseph Alexander b1895, Patrick b.1892, Josephine b.1897, Alma (Emma my g grandma) b. 1898, and I also think these children John b.1887, Albert b. 1888, William b. 1890, James b. 1891, Daniel b. 1894, May b. 1895.
I think but not positive that Elizabeth died in 1899 and Fred remarried Catherine Mahew (Mailloux), 14 Aug 1899. Who also went by Kate and Katherine. Then they had children Frederick b. 1902, Bernard b. 1904, Mary Anges b. 1906, Katherine Rose b. 1908, Mary Susan b. 1911, Annabella b. 1914. That was a suspicion of someone else I talked to, but I haven't been able to confirm it. I did find the marriage reg for Fred and Catherine. But it did not say if he was single or widowed.
I haven't been able to find any records for Fred and Elizabeth other then their children birth records in the NB archive website. I haven't had any luck finding a marriage reg for Fred and Elizabeth yet.
Their daughter Alma (Emma) married Oscar Anderson from Sweden in 1914. Oscar died in 1921 not long after returning from WW1. Alma remarried Roy Robinson a few years later. I have found the birth reg and also the marriage registrations for Alma Emma online. Just including the info in case it's helpful.
My main snag has been in not being able to find a marriage reg for Fred and Elisabeth. I'm guessing it would be around 1885 biased on the age of the eldest child. I'm hoping that if I can find it, it will list their parents names.
If anyone has any info on the family, especially Fred and Elizabeth would be very much appreciated! This side of the family has been really hard to track down.
Thanks,
