Hi Richard,
I have a little more information for you, but unfortunately I did not make a note of Josephe FRIQUES' parents names. The Drouin says she married at Ile-du-pas, and Mariages du Comte de Berthier lists it as simply "Berthier," on 28 Oct. 1823 to Benjamin Benoit CAYER.
This FRIQUE name is also found as TRINQUE or TRINGE, and in the USA, as FREDRICK.
Found in St-Cuthbert for the 1881 Census:
Benoit CAYER Mar. Male French 80 Quebec Rentier Catholique
Josette FEDERIE Mar. Female French 81 Quebec Rentier Catholique
They are living next door to their son Pierre and his wife, Louise Patrie.
From Mariages du Comte de Berthier, Lucien Rivest: Montreal 1966:
Benjamin CAYER m. Adeline LESSARD on 4 July 1859 at St-Cuthbert.
I found information for 3 children, siblings to your Florida:
Louis CAYER m. Olivine AYOTTE on 24 Jan. 1881 at St-Barthelemy.
Calixte CAYER, b. about Aug. 1868, died 2 Jan. 1869 at St-Barthelemy.
Joseph-Benjamin CAYER, b. 9 May 1872 at St-Barthelemy, died 26 Feb 1947 at Woonsocket, RI. He married in Woonsocket, Josephine CREPEAU on 23 Nov. 1896
Adeline LESSARD died before Jan. 1879, because Benjamin CAYER, widower, married Adeline ALLARD. (I did not make a note of her parents) on 21 Jan. 1879 at St-Berthelemy.
I know of one son for this couple, therefore a half-brother to your Florida:
Wilfred CAYER, b. about Aug 1880, m. Julianna TRUDEL on 10 Sept 1900 at St-Bathelemy. This couple had at least 7 children at St-Barthelemy, and Wilfred died there in 1954.
From: Saint-Barthelemy Comte de Berthier 1828-1992 Tome 3, (Societe Genealogique de Lanaudiere), p 77 - Benjamin CAYER died on 19 Jan. 1918.
I hope this opens up new research for you.
Regards,
Shari
