I have come across duplicate categories.

Question

Under “Immigrant Ships” is a category for Immigrant ships to America and then another category for Immigrant ships to United States. Should these not be merged?

Comments

To save time for people considering this question, here are the links:

• Category: Immigrant Ships to America
• Category: Immigrant Ships to the United States

Answer 1

It's my opinion they should not be merged because:

Immigrant ships to America = before 1776

Immigrants to the United States = after 1776.

Hope it helps!

That might be a good reason for not merging.

I don't know who handles the Immigrant Ship categories, but if this is the official reasoning, it needs to be described in the categories, and there needs to be official dates, and a next/previous relationship set. Probably this needs an infobox?

Answer 2

Immigrant ships to America should probably be renamed to something like Immigrant ships to English colonies, pre-1776, as that is all that is found as sub-categories (America is a big place, not just comprised of modern USA).  Immigrant ships to USA is not the same, so no merging.

Comments

"English Colonies, Pre-1776" isn't sufficient to identify the Thirteen English or British Colonies in North America (also known as the Thirteen American Colonies), cf. English overseas possessions.

that's fine by me, it was just a suggestion as to what it should be changed to, not cast in concrete.
