I had done a lot of genealogy and had traced relatives back to the UK, Jamestown, Mayflower and pre revolutionary war.
A sibling has a daughter really into genealogy, and the sib paid for a year of Ancestor.com and a DNA test as a gift to me, this past Christmas.
My wife and I are basically in our 80’s and our adult children are in their 50’s. So, we discussed if they were okay with me doing the DNA testing.
Everyone said to do it, and I did this spring. My DNA has identified a few hundred living cousins, which we knew nothing about.
In about 6 months, my ancestral DNA printout has shifted from a fairly wide balance to basically UK/Scotland/Ireland and North west Europe, mainly France, Germany and Switzerland. My DNA didn’t change, but the # of DNA donors @ Ancestry.com has increased in size. I don’t really understand this, but that is what Ancestor.com has told us.

The Goode Ship Lyon, Master and Captain William Pierce, 1630-1635.
Ufford arrived on the good ship Lyon in September 1632 and was met in Boston by Winthrop himself. Roger Terrill, a young 18 YO on the ship, married Ufford's daughter Abigail who was also on the trip (I wonder what REALLY happened on the voyage?).
They all went on with William Pynchon to found the city of Springfield, Massachusetts in 1636, and then found and settled the city of Milford in 1639. Here's a marker on their grave:
