Here's another variation on the ring of oaks version.

Accrington Accrington is the main town of the Borough of Hyndburn named after the river which flows through a culvert beneath the Victorian shopping arcade. The name derives from the Old English words 'ęcern' & 'tun' meaning where acorns are found. The first recorded use of the name was prior to 1194 when it was recorded as 'Akarinton' by 1277 it had become 'Acrinton' and by 1311 had become 'Ackryngton' much as it is pronounced today. The town is located some 5 miles east of Blackburn and is synonymous with brickmaking.
No mention of any Saxon Lord called Inga there. In fact in the 'g' doesn't seem to have come into the name until 1311. The old English ęcern and tun seems more than plausible to me.
