Dear Roland, 
What remains is that Böhtlingk's family belonged to the Dutch merchant community in St. Petersburg. 
Whether or not his forefathers had adopted the Dutch nationality which at that time was practically the only way to be officially allowed to settle in the Russian empire depends on the archival evidence that can be found, minus coverup attempts that may have followed... There were very old Lutheran congregations in the Dutch republic preaching since the 16th century in 'Nederduits' -- grammatically standardized several centuries before 'Hochdeutsch' -- so the religious or even religious-linguistic affiliation need not be a decisive factor. 
N.B. the existence of a German Lutheran congregation in St. Petersburg in the early and mid-19th century should not be construed according to the political situation of middle Europe in the late 19th century, post-Bismarck. 
Best,
Jan Houben

According to the research of Agnes Stache-Weiske, this claim, which 
can be found in various places (e.g. Windisch, Kern, Mylius), is not 
true. It is correct that Böhtlingk's father belonged to the Dutch 
merchant community in St. Petersburg, but according to Stache-Weiske 
this says nothing about his nationality. A relatively sure indication, 
however, is the religious affiliation of the family, which from the 
beginning belonged to the German Lutheran congregation in St. 
Petersburg and not to the Dutch Reformed Church.

Böhtlingk's father only acquired Russian citizenship shortly before 
his death, but only for himself and not for his family. It was only 
when he was awarded the title of nobility that Otto Böhtlingk himself 
became a Russian citizen in 1888.

Compare Agnes Stache-Weiske: "... für die Wißenschaft, der ich von 
ganzer Seele lebe", Otto Böhtlingk (1815-1904): ein Gelehrtenleben, 
rekonstruiert und beschrieben anhand seiner Briefe, Wiesbaden: 
Harrassowitz 2017,, p. 12 f.

Best,
Roland Steiner
