Whatling Family Origins

The Angles, Saxons and Jutes moved into the British Isles during the 4th,5th and 6th centuries. This was before the Viking raids of the 7th and 8th centuries and Danish invasion and settlement in the 9th century.
In the 5th/6th.century a band of people crossed the North Sea from Europe to the British Isles. They knew where they were going as trading was and had taken place long before. They also would have had oral stories from their fore bearers who might have served in the Roman Legions. Without a shred of evidence I like to think that they were Angles, or possibly Jute in origin, rather than Saxon.

The Leader of this band was WACEAL, and those with him of the same tribe, clan, or group were the Waceal - ingas.
Ingas was not son of as in the Scottish Watson, but meaning the people of, or the followers of Waceal, so a member of this group would be referred to as Wacealingas.
As time past the name began to change form, the vowels hardening, or softening, plus the input from people of other tongues and one form was Waslin.
However,in 991 the Anglo Saxons fought the Danes at the Battle of Maldon, lead by Eaidorman Byrhtnoth. He was killed and the Anglo Saxons lost. Maldon which was sacked and pillaged.
In 1016 they again fought the Danes, who were led by Canute at the Battle of Ashlingdon. Eventually Canute became King, this only 50 years before the Battle of Hastings (there is an epic poem of the Battle of Maldon in the Saxon Chronicles).

The Lost Manor
It could well be that the Wacelin , Wasling line came to an end at either Maldon or Ashlingdon, among the fallen of The Flower of England.
As a result the Manor of Watlingeseta reverted back to the King, for Warcelin would have been a House Carl and be obliged to answer the Kings call to arms.
The earliest records are for Norfolk 1086, in the ‘Doomsday Book’. In this book is recorded the Manor of Watlingeseta in the Half Hundred of Diss.
Today scholars call it a lost Manor as it whereabouts are unknown. The Manor of Watlingeseta, it states, was held by the King (William, in 1086 and before 1066, Edward the Confessor).

Also recorded in the book is Wazalin who held land at Weeting, Norfolk, one of the few Anglo Saxons still holding land after William the Bastard and his bunch of land grabbing thugs won the Battle of Hastings.

Watling Street was built by the Romans during their occupation and the name came after the Roman period.,the present day town of St. Albans (Verulamium) was originally Waetlingacaester, but after the martyrdom of St.Alban the name changed.

St Albans Musuem have confirmed that the Waecelingas settled on the old roman site at St Albans circa 900AD, and indeed St Albans was called Waetlingacaester for many years.

WATLING STREET (Wikipeadia has lots more detail)
The original Celtic and Roman name for the road is unknown and the Romans may not have viewed it as a single path at all, dividing it amongst two separate itineraries in one 2nd-century list. The modern name instead derives from the Old English Wæcelinga Stræt, from a time when "street" (Latin: via strata) referred to any paved road and had no particular association with urban thoroughfares. The Waeclingas ("people of Waecla")[1] were a tribe in the St Albans area in the early medieval period[1][2] with an early name of the city being "Waetlingacaester", which would translate into modern English as "Watlingchester".
