The D'Arcy Archive
Portsea St Mary, Hampshire · coverage tested 13 September 2026

Two years of Portsea

The first record of this family ever found in England survives because it falls inside a transcript twenty-two months long. Nobody had checked how long the transcript was.

On 19 March 1780, at Portsea St Mary in Hampshire, a child called Joseph D'Arcy was baptised, son of Robert and Jean. It is the earliest English record this archive holds of the family, and it is the only document anywhere that names Major-General Robert D'Arcy as somebody's father. How it was found →

This page is not about that entry. It is about how much of Portsea's register stands behind it, which is a question that should have been asked first.

All 46 are baptisms. Not one burial. Not one marriage.

A separate control — John Smith, Hampshire, across the thirty years 1770 to 1800 — returns 137 entries from twenty-odd parishes and NOT ONE from Portsea.

FreeREG's Portsea St Mary transcript is baptisms, and it is essentially two years long: 1780 and 1781, with a single entry spilling into 1782. coverage established

What that means

  1. Joseph's baptism survives by two years. Had Robert and Jean christened him in 1779 or 1782, this archive would have no English record of the family at all, and the Hornby claim would still be the only thing on the page.
  2. The absence of his brothers and sisters means nothing. This archive has twice implied that Portsea produced one child and no others. It produced one child because the transcript covers twenty-two months. Any sibling born before 1780 or after 1781 is not missing; it was never transcribed.
  3. It is not a null result, and it was never tested as one. The rule on this site is that you establish coverage before you report an absence. That rule was applied to Berkeley, to Dursley, to Hanley and to eight counties of Sanigers. It was not applied here.
  4. The register itself is intact. Portsea St Mary's original books survive at Portsmouth History Centre and are filmed. The question is not whether the evidence exists. It is that nobody has read the volume — and a volume covering, say, 1770 to 1800 would test the whole household in an afternoon.
The find is not weakened. The silence around it is. Joseph D'Arcy was baptised at Portsea on 19 March 1780 to Robert and Jean, and that remains as solid as it was this morning — it is a parish register entry and it says what it says. What has changed is that this archive can no longer treat Portsea as a parish it has searched. It has searched twenty-two months of it. The volume to read → · Filed as an error →
