Matchmaking

I'm looking at various old church records and trying to fathom out my ancestors from the early to mid 1800's.

I know matchmaking was very common in rural Ireland and especially in Cork and Kerry. I'm wondering what were the traditions with regard to who moved from one townland to another.

I imagine that it was usual for the woman to move into the man's farm - is this correct?
If the man was a farm labourer with no land and similarly if the woman's family had no land would the woman or the man move?
Also did the wedding usually take place in the bride's or the groom's parish if they came from different parishes?

I can imagine that circumstances might dictate what happened in different situations but what was the usual custom?
