Let's start with
James Roy father of
James (c1850-1917), John (c1854-1909) and Thomas (1864-1889). The last mentioned is the grandfather of
Maurie Roy. James junior was born in Co Fermanagh, Ireland.
We have two possibilities for the first of these James. Both records indicate that he was a constable so we assume that it is the same person. The
Constabulary records list the date of appointment as 19 Jul 1837, aged "22" (meaning he was over 21). Year of birth (in Co Antrim) is therefore about 1815 - but see below. If born in 1815 he was 35 when he married and had his first son, and 49 when son Thomas was born. Other evidence suggests he was born in 1827.
There are two different marriage dates in 1850 but that is probably because one (5 Apr) was registered "on the quiet" since constables were not allowed to marry (and possibly because the bride was pregnant?). Their respective ages are listed as "22" but that is merely "code" for over 21. The other marriage (20 Dec) was celebrated once he had left the Constabulary (18 Dec)
The April Civil marriage records identifies the wife as Catherine Thompson and their respective fathers were both James and farmers. James Roy senior was 32 at the birth of his son in 1827.
So now we have
-
James 1 (b. about 1795),
-
James 2 (b. 1827?) and
-
James 3 (b. 1850).
We can probably assume that James 1 was from County Antrim since that is where James 2 was born.
All three James are a bit of a mystery. We know nothing about James 1 apart from being a farmer, what we know about James 2 is given above but the constabulary enrolment and birth dates need to be sorted out, and we know very little about James 3's family except for his wife and children - were there any grandchildren?
(We also know nothing about Catherine Thompson.)
