Citation Issues

I need to temporarily cite an entry in Ancestry's "New York, New York, U.S., Index to Death Certificates, 1862-1948" database.

Ancestry provide this information:

Source Citation

New York City Department of Records & Information Services; New York City, New York; New York City Death Certificates; Year: 1911

Source Information

Ancestry.com. New York, New York, U.S., Index to Death Certificates, 1862-1948 [database on-line]. Lehi, UT. USA: 2020.

When I add reference notes from two sources, but both relate to the same subject, I list them separately using two numbers. Is this correct?

Is the purpose of a short reference note to lead the reader directly to the source or lead the reader to the full reference note? The answer will help me in deciding what to include in a short note/ 

I've got a statement i'm making

In the Northumberland area there are numerous David Cockburn records in Tynemouth, North Shields, Wallsend, Wooler, Berwick-upon-Tweed, and others.

That obviously needs a source but it isn't for a single database or record it is from the entire website. So this is my attempt to cite the search.

When you have a table and you are putting the table citations in the last row of the table, can / should you use the short version of the citation?

One side of me says yes, the full citation is already in the document prior to the table so that is fine. The other side says, well the purpose of putting it in the table is so that if someone copies it, they have all the references.

I’m privately printing my maternal grandfather’s diary written in a Field Message Book during the first two years of WWI. Among other things, I’m including scans of items in my, or a relative’s, possession. In the Reference List at the end of the book, I’m really stumped how to word the first part of a citation for a letter from my grandfather, William Robert Bruce, to my grandmother, his wife, Ethel Sarah (Phelps) Bruce. I'll just be showing the first page where he mentions being gone, "a whole year; one long year of separation."

Dear Editor;

I've stumbled upon a case which, while no doubt covered by the EE book, absolutely defies my attempts to cobble together something sensible to use as a citation. There is; an emailed PDF of a manuscript transcription, an image copy that was transcribed and an original unfinished manuscript. There are just too many different types of citation elements to identify, generate and join together.

I would very much appreciate any advice that would help me plan how to attack the production of a citation to reflect the following.

The church that has records of some of my ancestors sent me photographs of pages from the church's sacramental record books. The books have no titles and no page numbers. Would this be the correct citation? 

I want to cite a household in an1892 NY census record for Auburn NY. However I run across two issues that I have questions on.

1. There is no page numbers. Does it matter if I use the term  n.p. or unnumbered pages ? Other than line number is there something I should add to guide person to this page?

2. There is no column for relationship to say who is head of household. Is it alright if I call out the first person in the family and use their name as the household name? 

Correct me if I am wrong. A "Source List" would look like this....

Book

Cemetery

Newspaper
