Fulco (bishop of Estonia)

In 1171, Pope Alexander III asked the Archbishop of Trondheim to assign an Estonian monk Nicolaus living in Stavanger to go to Fulco's assistance.

As the two bishops had similar names and they worked roughly around the same time in neighboring areas under Lund's missionary supervision,[9] possibility for the identification remains, although the church in Finland is officially sceptical about it.

If information about Folquinus still being in office in 1198 is correct, his identification with Fulco would require him to have worked in missionary assignments for more than 30 years, in any case reaching a rather high age for a man of his times.

In a letter by Pope Innocent III to Anders Sunesen, the Archbishop of Lund, in 1209,[12] an unnamed Bishop of Finland is mentioned to have died "lawfully" (i.e., a natural death) sometime earlier.

By repeating Archbishop's own words, the letter makes it clear that the dead bishop had been appointed by the Lund archbishopric or at least with its approval, and that the "recent" establishment of the church in Finland was work of the Danes or their close allies, "caretaking of a few noble men".
