sinisiltä
Sinisiltä is a Finnish surname. Its literal translation from Finnish is "blue bridges" or "blue bridge". As a surname, it is not exceptionally common but is present within Finland. Like many Finnish surnames, its origin can be traced back to the late 19th and early 20th centuries when many Finnish families adopted surnames, often based on nature, locations, or professions. The etymology suggests a possible connection to a geographical feature or a historical place where blue bridges were a notable element.

The distribution of the surname is primarily within Finland, though emigration may have led to its presence in other countries with Finnish diaspora communities.
