Historical parish links are strongest around Stockport, London parishes, Manchester, Childwall and Liverpool. These are the places where the surname stands out most clearly in the older records.

The modern local-area list points to Liverpool, Bradford, Suffolk Coastal and Cheshire East. Treat these as concentration signals, not proof that every family line began there.

Neighbourhood profile for Glennon

Modern surname records can be compared with neighbourhood classifications. For Glennon, this points to the kinds of places where the surname is most concentrated today.

These neighbourhood labels describe areas, not individual people. They are useful because surnames often cluster through family history, migration, housing patterns and local work. A surname can be strongest in one type of neighbourhood even when people with that name live across the country.

The UK classification gives the national picture. The London classification is more specific to the capital, where housing, age profile, tenure and population mix can look quite different from the rest of the UK.

Supergroup

Semi- and Un-Skilled Workforce

Read profile summary

Group profile

Many households in these neighbourhoods comprise separated or divorced single parents with dependent children. Residents are typically born in the UK, and these neighbourhoods have relatively few members of ethnic minorities. The prevalence of children, their parents and those at or above normal retirement age, suggests neighbourhood structures may be long-established. Levels of unpaid care are high, and long-term disability is more common than in the Supergroup as a whole. Use of the social rented sector is common, often in terraced houses. Levels of overcrowding are above the Supergroup average. Unemployment is high, while those in work are employed in elementary occupations such as caring, leisure and customer services. Many residents have low level qualifications. Neighbourhood concentrations of this Group are found in the South Wales Valleys, Belfast, Londonderry and the Central Lowlands of Scotland.

Wider pattern

Unemployment is above average. Residents are predominantly born in the UK, and residents are also predominantly from ethnic minorities. Social (but not private sector) rented sector housing is common. This Supergroup is found throughout the UK’s conurbations and industrial regions but is also an integral part of smaller towns.

Meaning and origin of Glennon

The surname Glennon has its origins in Ireland, where it first emerged as a Gaelic Irish name during the Middle Ages. It is derived from the Irish Gaelic word "glennan," which means "glen" or "valley." This suggests that the name may have originally referred to someone who lived in or near a valley or glen.

One of the earliest records of the name can be found in the Annals of Ulster, a chronicle of medieval Irish history. The entry for the year 1395 mentions a Donaldus Glennan, who was likely an early bearer of the Glennon surname.

During the 16th and 17th centuries, the name Glennon was particularly prevalent in County Armagh and County Fermanagh, in the northern part of Ireland. It is believed that the name may have originated in one of these counties, where many families bearing the surname resided.

In the late 16th century, a notable figure named Hugh Oge Glennon was recorded as the chief of the Glennon clan in County Fermanagh. This suggests that the Glennons were a prominent family in the area during that time period.

Another historical figure with the Glennon surname was William Glennon, who was born in County Armagh in 1776. He was a prominent Irish Catholic priest and educator, and served as the president of the Royal College of St. Patrick in Maynooth, Ireland, from 1813 to 1837.

In the 19th century, the Glennon name spread beyond Ireland as many Irish families emigrated to other parts of the world, including the United States, Canada, and Australia. One notable bearer of the name was Richard Glennon, who was born in County Fermanagh in 1849 and later became the Archbishop of St. Louis, Missouri, serving from 1903 to 1946.

Other notable individuals with the Glennon surname include Brendan Glennon (1913-1995), an Irish playwright and novelist, and John Joseph Glennon (1862-1946), an American prelate who served as the Archbishop of St. Louis from 1903 to 1946.

While the Glennon surname has roots in Ireland, it has since become more widely dispersed across various parts of the world, with many families continuing to bear this name and its various spelling variations.
