Would the family have something to do with the Kiseleffs who lived in the Grand Duchy of Finland? They are fairly well known.
In Helsinki there is a famous neoclassical building called Kiseleff Bazaar (Kiseleff's Bazaar) which was built by a merchant with the name Kiseleff.
Here you have a large picture of it:
http://www.korttelit.fi/rakennus.php/id/469There was also consul Feodor Kiseleff, who with his brothers inherited the sugar factory in Töölö (Helsinki). He had a number of state and honour duties. Because of his position his wife Amalia Kiseleff (née Mattheiszen) became one of the ladies-in-waiting of Empress Maria Alexandrovna around the Diet 1863.
They didn't get any children but their manor in Alberga was a still full of life because the children of Emilia, the sister of Amalia, visited it frequently. There were also evenings with music arranged at Alberga.
Funny thing, I found a link to an address calender of Helsinki from 1889. There were this many Kiseleffs listed:
