I tried to look at Lancashire Archives catalogue last night but it was down for maintenance. I normally use the "Advanced Search " facility and enter a key word, usually a surname or a place. Other times I've found things using Simple Search.
I've looked at Lancs. Archives catalogue again.
1718 probate ,William Hallithorn, Kirkby, Kendal. He was an innkeeper.
1722 probate, Ann Halithorn, widow of William, Kirkby, Kendal.
Search engine doesn't allow for phonetic spellings.
Nothing for Holythorn.
