If John and Alice were located in over Darwen(which is what I have come up with on ancestry), then according to the records Alice was Alice Marsden....the only thing about this is that John and Alice Married on january 2nd 1815...Daniel was baptised 27th June 1813(according to Bishops transcripts).
If these are the right ancestors then I think I might have found parents for both John and Alice
If I am on the right John walsh he was born 21st of March 1790.
This has just been a quick and cursory search. If you have any more details about John and Alice that would confirm what I have found so far, then these would help greatly in a more detailed search.
I might have a look at census details sometime over the weekend.

I should add that I am no expert in hunting down ancestors...and the further back you go the harder it is to confirm accurately that the details are correct.
Back in the times when these people lived the details of lineage were documented in family bibles...but these weree often big, heavy and dumped because no one wanted them.
Please let me know if you think I am on the right track.
