Did they marry in 2 separate churches on the same day ?

The problem here is that there is an old church dedicated to St Tanwg's at Llandanwg, situated just behind the beach in the sand dunes and close to Shell Island. The church was falling into ruin in the 1840s and a new church was built in Harlech and since this church was intended to replace the early church it too was dedicated to St Tanwg. In 1884, following a public outcry, the roof was replaced on St Tanwg's Church so there are 2 churches within a distance of 2 miles and both dedicated to St Tanwg.

Matters become more complicated because Llandanwg is not only the name of a small village but is also the name of a parish. Harlech, for example, is in the parish of Llandanwg.

Thanks for this.  A further complication seems to be that the original parish church was right on the edge of Llandanwg parish - not very conveniently placed for the parishioners of Llandanwg but very convenient for the parishioners of the neighbouring parish of Llanfair. Many people from Llanfair seem to have some of their children baptised in Llanfair and some in Llandanwg - it all yets very confusing.

I notice those two places are aprox. 5 miles apart, one being one mile from Harlech and the other church being 2 miles from Harlech.

By law banns have to be called 3 times in the parish where the bride live and 3 times in the parish where the groom live.   I have a similar situation with my ancestors up in Scotland 1850 where the groom's wedding banns announcement to his bride (name given) together with his address was noted in his Glasgow parish church and the brides's solemnised marriage to the groom plus her address was recorded in her Tollcross Parish Church.
