My Ancestry results changed from 25% British, 25% Swedish and the rest a Northern European mix to 23% German, 21% Central European, 17% Danish and blessed be 11% Scottish, plus a mix of European bits and bobs. Quite a change but at the same time nothing really new as from family I've always understood my mom's side to be Danish and German and my dad's side to be English and Norwegian, with a bit of French mixed in from his mom.
One of my brothers did genealogy research quite a while ago on the Fisk side but I've always felt he got to a point where he tapped in to work a Lewellen Fisk had done but didn't necessarily track our lineage in it. There were several Fisk's in Salem at the time of the witch trials, Charles was a doctor and Thomas was a lawyer who sat on the jury of the last trial and then wrote a dissertation on why the verdict was wrong.
As for tracing health, nothing stands out, except that both grandmothers had forms of dementia but they both lived until their late 80's.
I haven't had an interest in visiting Germany but would go if the opportunity arose. I do want to go to Scandinavia and am thinking it would be great to do so thru a cruise.
