@KaySands ,
I'm well aware of the hierarchical nature of location, but how insignificant are indications like "Europe Spain or France" when the perceived size of the visible world in the 16th and 19th century as less than 15 km in radius.
Allow me to explain the historic evolution in Belgium as an example; pls use the links below to get more info
*before the French occupation of the low countries 1792 (during the -feudal- Ancien Régime) there were cities (with charters, defences and freedoms, hence the name "vrijheid") and Low:countries ; Heerlijkheden (Herrschaften, or fiefdom of a feudal Lord) and both would have Hamlets on their territory. The cities, fiefs and their hamlets were part of the Earldoms, Counties, Duchies or Prince-Bishopries that answered to the King/Emperor
* During the French occupation Municipalities were created by the French Directoire : there were nearly 2800 administrative entities at municipal level and a hierarchy of cantons, arrondissements, departements and prefectures. Many of the rural municipalities were composed of several hamlets and a main village (until they had about 5000 inhabitants)
*Those municipalities were maintained after the independance of belgium in 1830 , and for Belgium grouped in Arrondissements and Provinces (Wikipedia (ENG) : municipalities of Belgium ) and from 2800 we went to about 1700 in 1970 are now we are at just under 600. Naming is therefore date dependant, a location might change names quicker that some people changed trouser in rural flanders a century or more ago...
Given the ways in which people were named in rural areas with patronymics, names based origin from topo-/geographic locations, crafts or trades, and given the fact that many hamlets had the same name but were attached to a different fief or city, and that people with a patronymic name changed names after they moved to another city complicates that matter.
I researched a man named after his father Diederickssone, who moved form kortijk to Utrecht where he was named "Diederickszoon van Cortrycke" in all kinds of documents.
Therefore using the correct name for a location is paramount and trumps the want for an approximated birth location. Accuracy of location weighs in as more important that the lack of location.
A marriage act (of say the municipality of "Waarloos") could mention that the father of the groom was "from St Catherine's" , now we could assume that he's from a hamlet by that name ( one of the hamlets of "St Cathelijne Waver", which is a municipality adjacent to "Waarloos"), while in reality he's form several dozens of kilometers away, when we look for his birth certificate in the adjacent municipality we might find a man by a similar name at birthday that roughly matches the age mentioned in the act. the combined errors links a man who is not the father of the groom but could be anything from a family member more than 5 generations apart, to impossble to discern a family link at all ...
By comparison the fact that he was born in Europe is irrelevant, except for the relatives of an emigrated family branch,
Ff both of those men were born in the Duchy of Brabant which covered approx 10.000 km2, they could be more then 100 km apart
but the location of Duchy of Brabant is still a useless identifier to distinguish those men people
You may think that Iḿ talking about an oddball example, as a matter of iḿ not. Before 1800 about 30% of marriages remained unregistered, were unmarried couples who acted like they were married and registered their kids and deaths. Another 10 % lied about their identity or origins at marriage and another 10% changed their names in the course of their lives, prisoners would lie about their names and origins etc. Error would already occur for people living in different hamlets outside the main village of municipality.
In my research I found that about 60% of people in marriage registers would be locally born ( that is in the same jurisdiction), less than 15 % of the cases bride and groom would be both locally born and their parents too. The data from other jurisdictions would not be verified for the parents only for the bride an groom a birth certificate was needed.
The result is that the collected data are hearsay and dependant on the correct recollection of the bride or groom of data of his parents, the correct pronounciation of the location by the groom or bride and the correct understanding by the acting registrar of the data , imho that is 1/8 chances that the data transmitted is actually correctly represented on paper, (and that is without the possibility of errors while translating/reading handwritten acts form microfilm) and we may be lucky that so much of the info is still useful
The fact that a person lived from date1 -> date2 in location ABC with a certainty of over 50% is far more relevant
I spoke about the low countries (which is contemporary Belgium Netherlands Luxemburg north of France and the German Rhineland). But i'm under the distinct impression that the same is true for most of Europe, including the UK , just to cite one example is the naming convention for London : the Boroughs, the Counties etc over time...
