Nice name.....
.com & .net forward to Sky History on the co.uk
.org is developed
.de is developed and owned by the history channel
.info developed
I could probably keep going but it's registered in 282 extensions.........
Combining "History" with .io is not hard to do......the below is under construction, but the description gives you an idea
History Ledger ( .net ) - History Ledger is a verified news and history site to help promote truth in social media and help stop fake news with blockchain technology
History App, Dapp, digital content or streaming service
A few ideas below as well.......
"Genealogy and technology—it’s a perfect blend"

Lot's of potential uses.......
I would be looking for mid - high xx,xxx
Maybe even low xxx,xxx further down the road to the right end user - .io prices keep going from strength to strength and all the main extensions are not going to be available........
I could be wrong on the pricing though, hopefully someone else jumps in.......
