suspect Willim born 1805 was s/o james Kennaugh + Christian Quine
James I think was son of John Kennaugh bapt Pat 1766-01-05 (taken from Bishops Transcripts) - I'm not sure of mother - it looks like a second marriage for John but I havn't looked at all the relevant Patrick Kennaugh/Kenna wills which you would need to do
Christian Quine was I think d/o Wm Quine + Margt Halsall bapt Patrick 1772-11-08 but there is an active Quine researcher who may have this line further back
