I have a lot of dutch ancestry too. pretty much cover all of Europe. on my name line my 3rd great grand father is currently my focus and currently a dead end.. born in 1799 Connecticut and died 1881 New York. Thomas Rogers. I have found 5 other Rogers that tie in to his line though, 2 of which I have traced those Rogers back to the king of Cicely.
His wifes mother was a Van patten (dutch) and multiple dutch lines on that side. they were the founders of Schenectady New Netherlands (new york), quakenbosch, shomerhorn, conyn, bradt, hemmstraat and many more
pretty much all the royals go back to Charlemagne, I have multiple lines that route to him as well
This guy has some great videos on the royal linages https://www.youtube.com/@UsefulCharts
