Hi Vanessa, Your friend may already have this information. l found on findmypast In the Leeds Mercury June 18th 1842 the birth of a daughter to James Garnett of Mill House Bradford.
Also in the Bradford Daily Telegraph Friday 6th January 1888 the obituary for William Garnett which mentions James Garnett. William was the senior partner for William Garnett & Co. which was the oldest company established by James Garnett early 1800s. The first mill was at Paper Hall Court Bradford.Three years later he opened a mill at Barkerend and was joined by his elder brother William (father of deceased) and sons Richard,James and William.James sen died in 1828 and William died in 1834. The business was carried on by Richard, James and William (deceased). Richard died in 1848 and James in 1850. James (Jun) left his son James as a member of the firm.
Hope this helps. Although very
confusing with repetition of names.
