Group A runes were most common in Viking Age Denmark
Barni
Old Norse Barni (m.)
An Old Norse male name Barni is not certainly found in Scandinavia, although it may be attested in some Danish place-names. An alternative explanation is that Barni is an Anglo-Scandinavian variant of the very common male name Bjarni. The name forms the first element of two places in Nottinghamshire called Barnby.
