I think it should point to https://en.wikipedia.org/wiki/Christopher_Polhem
"Bellmans" very likely refers to https://en.wikipedia.org/wiki/Carl_Michael_Bellman
Ulricehamn is named in honour of Queen Ulrica Eleonora, https://en.wikipedia.org/wiki/Ulricehamn but I can see how a street containing "Ulricehamn" may be more directly named after the city.
"Sankt Pers" is an older Swedish term for St. Peter. https://sv.wikipedia.org/wiki/Petrus
"Sankt Eriks" is https://en.wikipedia.org/wiki/Eric_IX_of_Sweden
"Nordenskiölds" is difficult since it can refer to several members of the family. https://en.wikipedia.org/wiki/Nordenski%C3%B6ld_(surname) including (and most likely) https://en.wikipedia.org/wiki/Adolf_Erik_Nordenski%C3%B6ld .
"Olof Palme" is https://en.wikipedia.org/wiki/Olof_Palme with at least 5 streets in Google Maps (the entry has a "3", which I guess is the number of entries in the source data).
"Strindberg" is https://en.wikipedia.org/wiki/August_Strindberg
The Tegnérsgatan in Stockholm is named after https://en.wikipedia.org/wiki/Esaias_Tegn%C3%A9r (connection written at https://sv.wikipedia.org/wiki/Tegn%C3%A9rgatan). There are at least 5 different cities with a Tegnérsgatan.
Also, in the US data "Santa Fe", "St. Francis", and "San Francisco" all refer to Saint Francis of Assisi.
"The name "Santa Fe" means 'Holy Faith' in Spanish, and the city's full name as founded remains La Villa Real de la Santa Fé de San Francisco de Asís ('The Royal Town of the Holy Faith of Saint Francis of Assisi').[5][6]" from https://en.wikipedia.org/wiki/Santa_Fe%2C_New_Mexico
"San Francisco was founded on June 29, 1776, when settlers from New Spain established the Presidio of San Francisco at the Golden Gate, and the Mission San Francisco de Asís a few miles away, both named for Francis of Assisi." from https://en.wikipedia.org/wiki/San_Francisco
"Sir Francis Drake" is https://en.wikipedia.org/wiki/Francis_Drake .
The author has take on a very heavy mantle. This is not a task that can easily be automated. Two streets with the same name may easily be named after two different people.
