Linda, are you saying that there are two Thomas Chalenors?
one baptised at Isycoed in June 1782
whose Father was Thomas Chalenor 1751-1827
and Mother was Elizabeth Peck 1753-1817
the other baptised in Holt in December 1780
and later married Elizabeth Hughes in 1806 then Elizabeth Ellis in 1824
whose father was Charles Chalenor and mother Mary Matthews
I have Thomas Chalenor 1780-1825 married to Ann Thomas 1776-?

Son William born Dec 16 1807 at Mancott, baptised Jan 24 1808, married Ann Lewis at Hawarden 26 May 1828
His father was Charles Chalenor 1745-?

married to Mary Matthews 1748-1807 Charles being the Great Grandson of Timothy Chalenr 1666-??? and Ann Wilme 1677-1731
It is a pity we cannot shoe extracts from our trees via this forum which would make comparison much easier
died Gt Boughton 1852
