Citation Issues

I just returned from a lovely research voyage to the Nova Scotia Archives and I am working through my finds to create source citations and add information to my genealogy databases. Most of the items I located are taken from microfilm, some created by the archive itself and others acquired from other places like GSU. The microfilmed records have their own issues, but aren't really that tricky, I think. Should I identify them by the roll numbers assigned by the Nova Scotia Archives, even if they are filmed by GSU or FHL? Should I include both if necessary?

I recently found a reference on Ancestry to a marriage record I have difficulty finding.  It was a database, and with the information provided, I was able to contact the county clerk's office and quickly received an email copy with the information provide.  I think what is important was that I had previously contacted the county clerk's office directly and they had performed a search for me that came up negative. But once I had the Ancestry information, mispellings and all, they were able to find the record almost immediately.

I’m trying to figure out how to properly cite Slave Registers of former British Colonial Dependencies, 1813-1834 on Ancestry.

Since Ancestry categorizes this collection as a census, I’m wondering if I should cite it as I have below. I’m using 6.51, citing an English census online database (Jamaica was a colony of the United Kingdom at the time of the record being cited).  

Source list entry:

I have just (after much waiting) received a copy of the contents of an alien registration file directly from the Department of Homeland Security. I'm a bit stymied as to the best format for citing this. Would the format for the Railroad Retirement Board or the SSA be the most pertinent examples? Everything else in the national government records section (chapter 11) seem to be NARA, LOC, or similar archive materials or they are CD/on-line materials.

While working on my ProGen Evidence Analysis assignment I have uncovered an error on one of the census records I'm using and now have no idea how to do my final citation. 

It was supposed to be easy. I was looking for the Asa Phelps household in Franklin County in the 1850 US Census. (I am using FamilySearch in this example because of the “difficulty” introduced by the way Ancestry groups and displays census records.) When I did a record search using this information, I was pointed to the following image: https://www.familysearch.org/ark:/61903/3:1:S3HY-6S69-D52?i=135&cc=1401638.

Hello EE,

I was wondering if you could help me out on this one.

I am trying to cite the "Search Will Calendars" database with images (of transcripts) from the Public Record Office of Northern Ireland (PRONI). As a background, so you will not have to look it up:

I've been spending part of this Labor Day weekend doing a little genealogy and Ancestry had some "new to me" images online that has the marriage record of my 3x great-grandparents!  Yay!

I'm struggling with how to cite a record I purchased and downloaded from the Cambridge Family History Society website. They have a service known as "Ancestor Finder" which allows one to enter Surname, Parish/Placename, and/or Record Set to "look up transcriptions from all the Cambridgeshire Parish Records, a miscellany of Non-conformist Lists and the 1841, 1851, 1861 and 1871 census records." Once the search has been completed, one can purchase the results and download as PDF. My search turned up the following record:

Perhaps someone could give me their opinion on how to handle this particular piece of evidence [document attached]?

I am trying to describe and use as a reference, this document, specifically  for the date of birth of Delphine Grant. Here is what I have thus far:
