The oldest and by far the most numerous of the Barlow families originated in Lancashire, taking their name from a manor in the parish of Whalley, near the modern industrial center of Manchester; and near the point where the three counties of Lancashire, Yorkshire and Cheshire meet (click map for enlargement and see the red X). They descend from a 13th century knight, Sir Roger Barlow of Barlow, in the reign of Edward I.
The senior male line of the family continued in possession of the manor of Barlow for at least four centuries, with Thomas Barlow as lord of the manor in the reign of Charles II, in 1664.
The medieval coat of arms of the Lancashire Barlows was (in simple terms), a two-headed silver eagle on a black shield, very similar to the arms of the German emperors, still used, I think, as the arms of West Germany.
Some of the junior branches of the family produced some individuals of moderate importance--a Bishop of Rochester (1603), an Archbishop of Tuam in the Church of Ireland (1634), the ancestor of a Lord Mayor of Dublin (1715).
Records of descendants of more modest pretensions include:
- __ George Barlow, a baker in Manchester in 1583.
- __ Henry Barlow of Derbyshire, a student at Oxford in 1584.
- __ John Barlow of Cheshire, another Oxford student in 1600.
- __ Sir Alexander Barlow, Knight of Barlow, whose Will was probated in 1620 at Chester. (Whalley Parish, in which the manor of Barlow was situated, was in the diocese and archdeaconry of Chester).
The Reverend Canon C.W. Bardsley, who was a rector of a city parish in Manchester for 30 years, published his authoritative A Dictionary of English and Welsh Surnames in 1896, and he remarked in it that the Barlow name in Lancashire "has ramified (definition: spread, branched out) in an extraordinary manner."
The 1873 Post Office Directory for Lancashire listed 75 Barlow householders in the city of Manchester. Other directories of the period listed 15 Barlow householders in the West Riding of Yorkshire; and 33 in the city of London.
