Confused Welshman keeping two daughters (6)
I believe the answer is:
addled
'confused' is the definition.
(addling is a kind of confusing)
'welshman keeping two daughters' is the wordplay.
'two daughters' can mean two replacements for 'daughters'.
'welshman' becomes 'aled' (common Welsh name).
'keeping' indicates putting letters inside (some letters kept inside).
'daughters' becomes 'd' (genealogical abbreviation for daughters).
'daughters' becomes 'd' (genealogical abbreviation for daughters).
'd'+'d'='dd'
'aled' enclosing 'dd' is 'ADDLED'.
(Other definitions for addled that I've seen before include "Rotten; muddled" , "Completely confused" , "Confused like infertile egg" , "Of egg, rotten and producing no chick" , "Confused (wits); made rotten" .)
