Reinsurance brokers Holborn Corp. of New York and W.J. Lehrke Co. of Edina, Minnesota, have agreed to merge.

Details were not disclosed.

The combined firm will operate under the Holborn name and all current Lehrke personnel will consolidate with those in Holborn’s Minneapolis office headed by Tom Frank, according to the announcement.

Holborn Corp. , which was founded in 1920, has been owned by its employees since 1998. Frank T. Harrison is CEO.

Earlier this month, Holborn Corp. acquired an ownership stake in Stonybrook Capital LLC, an investment banking advisor for the insurance and reinsurance industries.
