Hello Eric
I have found 8 Patrick Killips that are likely ancestors. I have found a lot of info on the Killips from Killip site but it does contain a lot of the mistakes found elsewhere. it's a place to start though.I have had help with some info from this board and have read a lot of wills that are available on Brian Lawsons site. I will post what I have here and stress that most is not verified but you may have more luck checking it out.

I have - Patrick Killip 1643 - 1712 Ballaugh marr. 1677 Kath Gell, marr 1680 Christian Looney, marr 1694 Mary Cottier.

Children of Christian Looney were
John 1682
Ewan 1689
Katherine
Patrick 1687

This Patrick 1687 marr Isabel Quay

Their son Patrick 1718 marr Mary Christian 1738 she died 1739.
He than marr 1742 Jane Kermode 1721 - 1790
They had 9 children

Of these William 1767 - 1835 marr Jane Kewley
Their daughter Ann marr JJohn Skillicorn. These were my gt gt gt grand parents.

The Patrick Killips I have found, I will list here as it may be of help.
