The Kilpatrick Surname Study
The 1881 Census of Scotland
Distribution and Intensity
The "contemporary distribution" (1881) of the
Kilpatrick surname is in line with the
etymological description. The surname is
strongly localized in Dunbartonshire where we
find the place name elements and parish
boundaries. The surrounding counties of
Renfrewshire and Ayrshire are also well
represented. In the 18th and 19th centuries,
industrialization and urbanization have distorted the historic pattern, with the
proximity to Glasgow being a major factor.
A further factor pointing to the Dunbartonshire origin can be gleaned from the
Kilpatrick Family Tree YDNA Study. Numerous instances of matches with the
surname Colhoun are found in the results. The distribution of the Calhoun surname is
geographically coincident with the Kilpatrick surname. Both Calhoun and Colhoun,
are variants of the surname Colquhoun. The Colquhoun clan territory overlaps in part
the parish of Old Kilpatrick. The shared DNA would likely pre-date the adoption of
surnames. Related individuals would eventually take surnames from different roots,
some as members of a clan, others who resided near a church.
Transcription confusion between Kilpatrick and Kirkpatrick likely took place n the
homeland before surnames became fossilized. This could account for the presence of
both surnames and the DNA overlap between the two surnames.
Surname Intensity
As mentioned earlier, the contemporary distribution of surnames during the late
19th and early 20th centuries has been significantly influenced by industrialization
and urbanization, making it challenging to trace a surname's historic origins
accurately.
An alternative method for examining this distribution
involves displaying it as an area fill map, normalized per
100,000 population. The advantage of this approach is that
the maps accurately represent the spatial extent of the
distribution. A refinement of this method involves
calculating a Banwell index, which compares the local
intensity of surname occurrences with the national
frequency. For instance, a Banwell index value of 5 would
indicate that the intensity of occurrences in a particular Poor
Law Union was five times higher than the national average
for that surname.
This approach helps eliminate urban bias and highlights two
distinct regions: coastal Ayrshire and the counties bordering
the River Clyde. When combined, these regions cover the
historic homeland identified by Black in 'The Surnames of
Scotland'."
Farmers and the Distribution of Surnames
In 1890, H.B. Guppy published "Homes of Family Names in Great Britain," wherein
he proposed a theory that farmers in the West of England could serve as identifiers
of the homeland for local surnames. Remarkably simple yet insightful, Guppy
utilized trade directories to analyze the distribution of surnames. His argument
rested on the premise that farmers, being the most stable segment of the population,
could pinpoint the homeland associated with a surname.
While modern surname studies have generally confirmed Guppy's principle,
allowances must be made to accommodate the gradual drift away from a surname's
homeland over time. The surnames Kilpatrick and Kirkpatrick provide an excellent
illustration of this principle.
Kilpatrick/Kirkpatrick Farmers
A query of the 1841 Census of Scotland
revealed 20 Kilpatrick and 29 Kirkpatrick
farmers, with none appearing in the
parishes of Old and New Kilpatrick. This
highlights a limitation of Guppy's approach,
as some farmers, whom we might term
"ghost farmers," have departed the land
without leaving evidence of their past presence.
The majority of farmers are concentrated in
Galloway, particularly in regions where
Kirkpatrick and a small cluster of
Kilpatricks are found. This aligns with the
dominance of Kirkpatricks in West
Dumfries in 1881, as indicated by the
distribution of the Kirkpatrick population in
1841, which corresponds well with the 1881
area fill map. Kirkpatrick farmers are
concentrated in northwest Dumfries, while
the broader Kirkpatrick population is
centered in southwest Dumfries-shire,
closer to the coast and the Solway Firth. As
noted by Davis Hey, younger populations
tend to migrate away from farms to settle
near market towns, such as coastal ports in
this case.
The information gleaned from the 1841
census of farmers allows us to trace their
existence beyond the census itself, including
their ages and possibly their birth locations.
It is likely that they are the sons of farmers
who preceded them. The question remains:
how far back can these familial links be
extended? It is reasonable to assume that
farmers in this region were present in the
latter half of the 18th century and almost certainly at the time of the plantation itself.
However, the presence of a cluster of Kilpatricks and farmers in Wigtownshire
requires further explanation. It is probable that these Kilpatricks are immigrants
from County Down, which is less than 20 miles away across the narrow sea from
Scotland. This will be explored in more detail when examining the Plantation of
Ulster and settlement from Scotland to Ulster.
The Kilpatrick Surname Study
Calculating the Banwell index:
The index compares the frequency and intensity of a surname at the
national level with the frequency at the local level, for example a parish or
a Poor Law Union. So if a given surname was calculated to be .1% of the
national population and .7% of a parish population, the index would be
.5% / .1% = 5 or 5 times as intense at the local level.
When mapping the Banwell index, it is common to observe the emergence
of a core area. As one moves away from this core, the values tend to
decline—a phenomenon geographers refer to as distance decay.
Areas of high intensity can be instrumental in identifying a surname's
homeland. It often takes several generations for core areas to fully
develop. By utilizing historical records, it may be possible to extend the
timeframe back to the early 1600s, providing deeper insights into the
origins and spread of surnames.
David Hey- Family Names and Family History
…. movement beyond the parish boundary was commonplace,
nevertheless most movement was restricted to a radius of between 20-25
miles, within an area bounded by the nearest market town. Much of the
movement in and out of parishes was by the young farm and domestic
servants and apprentices. Young people often returned upon inheriting the
family farm or cottage. Studies of communities and local societies in many
different parts of the country have emphasised the contrast between this
mobility and the stability of core groups of families over the generation.”
