Hi Private User, if you are already in project then I hope you saw it part where is a title: Czech Naming Conventions, some useful links, but also you can see and using a other useful:
How you said above they were born in Kingdom of Bohemia/České královstv, later was a Czechoslovakia, today is a one part is Czech Republic antohe part is Slovakia. Lots of peoples were migrated in different countries aorund World and their names was mentioend in the records at different language of that places, some of them were changed their names. E.g. in my researching, every person who was born in Czech Republic (and from a period of Kingdom of Bohemia), and I found it, a his/her name written at italian/german, I add name at english tab (default) of language of country where a person was born, also and other tabs of other languages of other countries. But for merging and find a possible duplicate if someone other also added, but in different form of the name, so I suggested previous to You.
Of course You can also use a AKA tab, where you can add also a different spelled names, if you found it at the records and sources.
In your example: for Josef's son Carl (Karel?) died in Swedish-speaking Finland, how you mentioned, in this case then for person at english tab need a setted a name how a person was mentioned when he/she died and burial at the cemetery, and at language of that country where is his/her last resident place, and how exactly name of them written at the grave. A other fields of language tabs in profiles, also You can use for add a names and surnames in other World languages.
Also for example place how you added: Přední Ovenec, Praha, Čechy, Austria, is incorrect if you want to see and based at World map of locations.
Přední Ovenec, was a place and part during the Austro-Hungarian Empire, which you can write about in the section About of the profile, but in the form of profile you need to add what the place is called today, how can be a profile located and showed based on today location map, if you are using a this option: https://www.geni.com/map
Also for information, I hope you have already read, if not, here is an explanation of one reason why any of the users of Geni must enter the correct geo-locations (today's locations) on the profiles, see the article on the Geni blog: https://www.geni.com/blog/research-based-on-genis-world-family-tree-featured-in-prestigical-journal-science-3100186.html (I shared from Croatia portal where we have this as Note for all users)
Again, as I already told you, for anything else or directions, and more details, you can seek advice from Tom, Honza or others. Do not hesitate to ask questions.
