Saying that Connecticut was 'part of' the New Netherlands was a major oversimplification, as the Dutch CLAIM extended to the Connecticut river, but excepting a few coastal settlements in the southwestern portion of the country, their control was completely nonexistent.
Yeah, but then again, there wasn't much to control back then.
now that you've revised the initial "well New Haven and Hartford kinda merged and there you go," implying that Hartford was its' own colony a la New Haven,
I said that mainly because New Haven and Hartford were co-capitals of Connecticut for almost 2 centuries.
