1778,  March 20th, at Castle-Townsend co. Cork, Laurence O’Brien, to Miss Hewitt, daughter of Henry Hewitt, Esq, Captain of the Beresford Revenue Cutter.

The Gentleman’s and London Magazine: Or Monthly Chronologer published in Dublin,  printed by John Exshaw in Dame Street.

Laurence O’Brien and Jane Hewitt are Henry Hewitt O’Bryen [1780-1836]’s parents, and John Roche O’Bryen‘s paternal grandparents, so in our case, great, great, great, great, grandparents. Jane Hewitt is also the reason for the Hewitt name occurring as a forename in the next four, or five generations

A Revenue Cutter was a Customs vessel and each cutter master was answerable to and received his sailing orders directly from the Collector of Customs of the port to which his ship was assigned. All crew pay, requests for supplies, arrangements for repairs to the cutter, and mission-specific tasking came directly from the port’s Customs House.

So great grandpa x 5 Henry Hewitt was a Customs Officer.
