Hi Brenda. I truly appreciate you taking the time to look into this. I am surprised That you found yet another Collier sibling born inth 1880s(James). I was aware of Henry Collier. The baptismal record shows a birthdate of 1887 and the 1921 census shows a birthdate of oct. 1889. I suppose inconsistencies are to be expected. Here is the household headed by Henry(Harry) Collier in the 1935 Census. It is interesting:
Collier Henry Head age --
Collier Annie wife age --
Collier Jim son age --
Collier Thomas son age --
Collier Charles son age --
Collier Joe son age--
Collier Clifford son age--
Collier Lizzie dau age --
Collier Pearl dau age 11
Collier Alma dau age 3
Collier Vivian dau age 3
Collier Susie dau age 5
Collier John H father/widow age 84

The John Henry with the three wives that you gave me info on was b.1851. He would have been 84 in 1935.I believe this is the same one.
would have been 84 in 1935. Henry Collier's Daughter Minnie b.1913 is not listed(she is on the 1921 census) she married a Cogan and had likely left home by 1935. She is still alive and may be able to tell us if her Grandfather JH spent time outside Codroy(I couldn't find a record of Susan Kendal's death either but i am limited to records available online).
Now as for the other sibling, Caroline Frances(Carrie), I was told that she married a Walter Fifield who was a warden on the Humber River in Nfld. I have the following from the 1921 Humbermouth Census(Carrie's year is shown as 1896 in the census but Tammy Hammond tells me this is an error and her actual birth year is 1886 which makes more sense):

Fifield,Walter Head b.sept 1883 Trinity
Fifield,Carrie Wife b.aug 1886 Codroy
Fifield,Emma,S dau b.Aug 1905 North Sydney
Fifield,Ethel Blanche dau b. Aug 1909 Belle Isle
Fidield William son b. sept.1911 Belle Isle
Fifield Walter son b. sept.1913 Humbermouth
Fifield Ida Doris dau b.dec 1917 Humbermouth
It makes sense that Carrie's first child was born in North Sydney.Carrie was away from family in Humbermouth and
and her sister Mary Ann lived in North Sydney.Both sisters
had their first child that year. It is interesting what you can
gather from looking at a census and dates and where people
were at a given time. One more thing. Carrie is listed on that Census as being born in Codroy. When I gave you that name I didn't know that her name was Caroline Francis(Frances?). Tammy Hammond gave me that information.I was also told that Mary Ann never went by that name she was always Minnie or Min.......and,,,if I do get that picture and my fingers are ALL crossed I will have a copy made and I will be only to happy to send it to you.
Regards
Brian
