Our Lavender family were originally hammer-men (i.e. forge workers) from the Hartlebury area in Worcestershire (near Kidderminster). Some of the family migrated to Shropshire, working and living in the area now known as Telford New Town, which includes Wellington and Madeley.
The family were in Wellington by the late 1780s and remained there until about 1816 when they moved to Oldswinford where my Great-Great Grandfather was born. He subsequently moved to Camberwell, London, marrying there twice in the 1840s before returning briefly to Madeley in about 1851, then moving to Netherton, in the Black Country (Staffordshire) in the mid 1850s, then on to Smethwick, near Birmingham by 1860. Shortly before his death in 1863, the family moved to live in Wednesbury where the family remained for some years. Samuel's son, Thomas (my Great Grandfather) had many children (as was usual in the later 19th century) and the family is now spread far and wide, though many still live within the Midlands.
One of Thomas Lavender's sons, Jack, founded the Lavender Aluminium works at Stone Cross, near Wednesbury, which survives unto this day (2000); many shares being held by Thomas's descendents. My grandmother, Jack's youngest sister subsequently moved to West Bromwich, Edgbaston and then to Harborne. Other Lavender descendents live in Wolverhampton, Cannock, New Zealand, California, Australia, Sussex, London, Sheffield, Leicester...
A vast amount of the information on the Lavender family in the Midlands has been provided by the research done by Colin & Enid Lavender.
