In Welsh's _English Literature_ is a "biography" of Tennyson which says,
amid various other slips, that he was born in 1810. Allibone's _Dictionary
of Authors_ (p. 2371) is a year out of the way. When this ponderous work
was first published, not much was definitely known of the poet, but
Alden's _Cyclopedia of Literature_ (1890), and other unreliable
authorities put 1810 or 1811 as the year of his birth.
In the parish registers of Somersby, Dr. Tennyson's handwriting records
Alfred's birth and baptism among the entries of 1809. Here is an instance
where one can put to flight a host--for the names of those who assign 1810
as the year of the poet's birth are legion.[34]
