Unable to find some of his father's executors, the charterless New Haven 'Colony' theocracy was forced into the larger Connecticut Colony in 1664 under political pressure from Charles II's England. Thus, New Haven 'Colony' and many other 'rogue' Puritan self-governing areas hiding regicides and without legal standing (for that is what they were) in the British Empire, were bundled into British chartered Connecticut Colony in 1664. However, instead of demoting New Haven power, it expanded it: the people there were still quite powerful since New Haven ('Colony'😉 was made a 'co-capital' of Connecticut in 1701, a status it retained unbelievably until 1873--nearly 100 years into the United States.
"Pre-Yale" Yale College (1701-1718) was actually stated in Old Saybrook instead of New Haven. It only relocated to this co-capital of New Haven in 1716 as the original founders were looking for more funds, and after New Haven had been made co-capital. It was renamed Yale College in 1718, now in New Haven.
Elihu Yale was sired from the line established by his Grandmother Ann Lloyd. His grandmother was the second marriage of New Haven 'Colony' founder and merchant Governor Theophilus Eaton. Elaborated below, another one of her grandsons was Edward Hopkins, heading the Governorship of Connecticut Colony before its consolidation as well, right next door.
There were 12 founders or rather “re-founders” of the New Haven’s Collegiate School of Connecticut (1701-1718) that became known renamed as Yale College in 1718/19 only a few years after the pre-Yale move there in 1716. Elihu Yale (d. 1721) is the most well known of the twelve. This is of course because he was the namesake choice of the college after he and others pumped it with some more funding. However, Elihu Yale being the namesake has generated an unfortunate artificial mystique around his presumed predominance, when he was only one of several later funders, and was not one of original founders of "Yale" at Old Saybrook. Besides, first, in 1999, the American Heritage magazine rated Elihu Yale the "most overrated philanthropist" in American history, arguing that the college that would later bear his name (Yale College, 1718-1873, then Yale University in 1873-present) was successful largely because of the generosity of another man entirely, named Jeremiah Dummer, but that the trustees of the school did not wish themselves to be known by the name "Dummer College".
Second, the all important Dummer was the one who really coddled London-based Elihu Yale to support Cotton Mather’s New Haven appeal in 1718 for more funds.
Third, there was perhaps a bloodline pull through Elihu Yale’s lineal relationships to the same political elite of the colony he was working with, through his grandmother Ann Lloyd who married the co-founder and first governor of 'rogue' New Haven 'Colony,' the London merchant Theophilus Eaton. Plus, fourth, one of her daughters, Anne, married Edward Hopkins in 1631--who was later a governor of Colonial Connecticut as well. In 1640 this other grandson of Ann Lloyd, Edward Hopkins, was elected Governor of the (still unconsolidated) Connecticut Colony.
Thus the "Yale" family was the politial administrator of both the separate New Haven 'Colony' and Connecticut Colony governments, from 1640. Between 1640-1655, since a man could only serve a one-year term as governor consecutively at the time, to get around this, Edward Hopkins and John Haynes (Connecticut's first governor, elected 1639) would trade off as governor (save one term by George Wyllys), each serving as Deputy Governor to the other when not governor.
Hopkins survived an assassination attempt in 1646 by a Native American tribe because Connecticut protected the chief of their rival tribe; he advocated an even larger New England Confederation (under his family's aegis); and made quite a bit of crony money while Governor with a variety of business interests throughout Connecticut. Hopkins even left Connecticut and returned to England often during his (rotating) stint as Governor. There he became (what year? during the Puritan Protectorate, 1651-59?) a commissioner of the Royal Navy (later admiralty commissioner), oversaw the printing of the still 'rogue' New Haven Colony's first laws under the Protectorate in 1658, and even concurrently served in Protectorate's English Parliament there.
