Thank you, can you tell me with respect to the entry for CRANE, Israel; Birth NJ Circa 1713, what do the initials of Rank: PS CS mean?

Also, according to Strykers, it was Israel Crane SENIOR, and not Israel Crane JUNIOR who was the Cornet Captain for Meeker. Stryker lists Israel JUNIOR as a private with Captain Stephen Marsh's light infantry.

How did DAR determine otherwise? Thanks, Jim Brengle
