Wow--thanks, y'all!
The spelling of these ladies' names is as found on other family records, but there's no reason a non-family member would know to report those eccentric versions.
Two things about the newspaper reports--no surprise that Dorothea's was so brief. It's believed that she emigrated to Ireland from British Columbia after the death of her second parent, in 1932, and I assume that her aunt was really her only connection in the community (they had lived at the rectory with several other Coopers decades previously, but that was in Co. Wexford).
Dorothea was, like Elinor, a "spinster," and at the time of Dorothea's death, Elinor was 83 years old, so probably not a lot of clubbing going on.
In her youth, Dorothea had appeared sometimes in community theatre productions, but otherwise had apparently been a dependent or served as a companion in wealthier families. There wasn't much point in an expansive obituary, for there was little to report and few to read it.
I was quite surprised by the probate record. First, what does the final sum reflect? Is that the value of the entire estate, or the entire estate minus any bequests specifically identified in the will?
Either way, £5,000 seems like a lot of money for 1939! Where had she gotten it all?? She was the last sibling standing, I guess...
Re the Thom's Directory reference: it includes a number next to each entry. Is that the annual rent, or some other fee?
I'm a little puzzled about the house. I'm used to "semi-detached" describing what we call a duplex, a single building comprising TWO homes with a single shared wall, but the street view seems to show terraced homes. Is it likely that the house has been rebuilt since its 1919 description?
I was thinking that 1919 was likely long before the Coopers moved in, but actually Aunt Vi had lived in the rectory nearly her whole life. I assume she had to leave on the death of her elder brother, which happened in 1920, so maybe she was the original tenant after its sale.
Still lots of trivial questions--but thanks to you, I now have lots more answers! Thanks again!

Thanks, Angela--good luck with yours as well! For the benefit of any other Kelly seekers, I am adding a photo of info Ms. Binions has posted at the cemetery.

Hi Lagavar--I'm delighted to see this topic is still active/accessible!
I'd be very interested in seeing the sales documentation for this farm. My sister and I visited Ireland/Northern Ireland last May (2017), and spent a brief time cruising Ballinlea Road; as you note, the buildings are not very visible from the road.
We also made a disappointing pilgrimage to PRONI, which, after scrolling through indexes and microfiche, yielded precisely one document: the record of the marriage of Duncan Ballentine and Rosetta (nee McLean) on 26 July 1894 at Ballintoy Parish Church (Diocese of Connor, Church of Ireland. This pretty church, which overlooks the coast, was built in 1813, and now unfortunately adjoins a road frequented by buses conveying visitors on Game of Thrones tours.) Do you have a family tree available to share? My most complete version is, like fergaine's, on Genes Reunited.

Cosmac, thanks for the additional cousins!
Polarbear, I am afraid the censuses are not especially helpful in the absence of the info Susano asked for.  Annie's troublesome: the only two pieces of info I've been able to find for her are the 1891 census, in which she is identified as an 11-year-old scholar, and Christina's destination report quoted above. 
Annie's two oldest siblings, Jane and Mary, were reportedly born in Dunse, Berwickshire; Annie was the first of the family born in Greenock.  I still haven't found birth records for J & M, which may mean their births weren't reported.  I do have marriage records for those two.
The only other thing I can say is that if Annie is called that twice, it's likely to be her actual birth name (i.e., it's not Ann or Anne).  For example, there's a sister called Bessie, and that's her name on her birth registration, not Elizabeth.
Annie's occupation, if pre-marriage, may well be "domestic", though some of her sisters apparently worked in a textile/wool processing factory.  With the canal and locks, I guess that Welland may have offered some of the same ship-supplying jobs that the men were familiar with from Clydeside.
But that's all I got for ya!
