William Cathcart of Dublin
Possible clues to his identity
More research needs to be done to nail down the identity of the two sons of John Cathcart (William and John) in the chart above. This chart was created from Robert Spann Cathcart's research in the 1960s. If we are to accept Robert's assertion, these two Cathcart brothers are very closely related to those of us who descend from the "Big 4." Since the most compelling bits of evidence I've found to date for John and his sons William and John (top right of chart) involve the William Cathcart highlighted above, he is the subject of this page.
The earliest clues as to William's identity are found in two advertisements published the Belfast Newsletter in 1759 (click for popup transcription). The William Cathcart (who is said to be living in New Row, Dublin) mentioned in these articles is trying to lease 63 acres of land owned by the late John Cathcart of Cloughmills. We can guess that William is serving as executor of John's estate and that John is either William's father or brother. Although we can't be sure exactly what relationship William and John share, it's very unlikely that they were distant cousins! At the least, these newspaper announcements tie a William Cathcart, merchant of New-row, Dublin with a recently-deceased John Cathcart from Cloughmills in County Antrim, Ireland.[1]
Before moving to the next clue involving William, let's address which John Cathcart is likely to be the one deceased in 1759 and whose estate included property in Cloughmills. We supposed that John was either William's brother or father because he's probably not William's first cousin, John Cathcart (to the left of William in the chart above). I say this because of 1) the mismatch in locations -- that John Cathcart is from Lavin not Cloughmills, and 2) because a first cousin certainly could serve as an executor, it's far from a common occurence. We can also eliminate the John Cathcart, alive (vivens) in 1799 on the bottom row of the chart, because that John Cathcart was not yet born in 1759.
The next clue we have regarding William is a memorial extract (Deed) registered Dec. 9, 1775 involving a William Cathcart, merchant of Dublin City. William gives 300 pounds worth of property for the benefit of his niece, Mary Murray, who plans to marry Richard Dobson (of Capel St., Dublin). Mary's father, William Murray is deceased at the time of this deed, and his estate is being administered by his executrix and wife, Rose [Cathcart] Murray of Armoy, County Antrim.

A contemporary wedding announcement provides the additional detail about William narrowing down his residence to "New-row" in Dublin. [2]
Occuring 16 years after the attempted leasing of land in County Antrim, it would appear safe to assume that the William Cathcart, merchant of New-Row in Dublin mentioned in both years are the same person.
Here are a few suppositions related to this transaction:
We may have to finally rely on DNA research to finally figure this all out! However, for the time being, I have two "prime suspects" as to the identity of the William highlighted above--and both of them married a woman named Mary.
