Where exactly did the marriage take place.
Where were both couples abode.
Who were the witnesses.
The marriage was in Wrexham register office. This is a little bit odd because everyone in the family that she married into (the Percivals) frequented and used Rossett church for every occasion. She wasn't pregnant (Harold didn't arrive for over a year) so I did wonder whether she possibly came from a catholic family. It was war time though so maybe this was the reason.
The addresses given are Harold's mother's house in Rossett for Mary and Acton Hall, Acton for Harold (this is a strange bit of information that my mum can't explain).
The witnesses were John and Mary Gibson, friends of Harold.
