Relatives of Ernest and Georgina Edwards (Nee Ward)

My grandmother would like to find any relatives of Mr and Mrs Edwards, her birth parents. Ernest was from Manchester and his wife from Dublin. It is believed Mrs Edwards had a brother called John who lived in Limerick where my grandmother and her twin sister were raised by Michael and Bridget Moloney. The twins were born in 1926 in Limerick. If anyone can help us to locate members of the Edwards or Ward families, we would be very grateful.
