Citation Issues

I am doing an indirect evidence case study to prove parentage. I want to mention that a survey of online trees was done but no tree was found with a source for the parental link between the two generations. I would like to simply cite the Ancestry Public Member Trees, FamilySearch Family Tree, and My Heritage Family Trees as a whole and not list every single tree that was examined. Is that a legit way to handle it? I think listing 40ish trees in a citation would be overkill but I thought I better check :) 

Hi,

I am on my fifth reading or so of your book and every time I read it or read through your blog, I seem to only get more confused.  I am a 100% Permanent & Totally Disabled Veteran, so it I do 95% of my research from home using Ancestry.com, MyHeritage.com, FamilySearch.com, etc....  While I would love to travel to all these amazing locations where so much data is held, it is just not that easy.  So these online providers are pretty much the best I can do.

I am working on citing a couple of immigration cards from Brazil. These cards can be found at Ancestry and FamilySearch. 

The way in which they are organized is a bit perplexing and can be confusing when you first look at them. There are two cards I am writing citations for. For clarification in my citations, I use FHL microfilm or DGS numbers instead of search paths. I do this because it is the fastest way for me to find the records at a later date.

Let me call and raise on a recently discussed item. I want to cite a section of a volume in a series (well, one of two series). What I've drafted for the first reference note is:

I have been doing genealogy for 20+ years and pretty much relied on the citations created by various software products (ancestry, MyHeritage, citation machine, etc...).  I am very much interested in making a change to a more consistent, descriptive and formalized citation style and have chosen EE.  I am struggling with this though as I want to convert over all my existing citations which I know will be lots of work, but I think the time is worth it.

Dear Editor,

Hello, sorry in case of bad grammar, english isn't my native language.
I'm struggling a bit with a good way to cite "Stammbücher" from Germany. These are bound books or folder-like books with preprinted certificate forms to get filled out from the officals when births, marriages, baptisms or deaths occur in the family, given to couples at their wedding from the bureau of vital records(or bought from the couple previously itself for the wedding).

Dear Editor;

To generate the source and reference statements for my parent's marriage certificate (image attached) as part of a collection; I've tried to follow the guidance of the 3rd edition of EE, "Privately held materials," section 3.25.

Some feedback on the following attempt would be appreciated:

(Note that [ADDRESS FOR PRIVATE USE,] is included as a placeholder for the full address in my personal version.)

The "Search the Online GRO Index" website has become one of my go-to sites for birth and death information in England. I realize the information given by the index is derivative and should serve as an interim source until more definitive evidence (i.e., the actual register) is obtained, but I would still like to cite it occasionally. Here's the format I've been using: 

I am attempting to correctly cite an entry from the 1911 England Census where the data is imaged from the National Archives and the database from which it came is Ancestry.com.

In drafting this, I referred to EE item 6.51 (online database entries), various references in EE to layering, and other guidance on this site.  

I came up with two possibilities.  The first seems like too much information and the second, I feel I'm missing something:
