Thanks for reminding me of that very useful website. I've managed to find William Miller's christening on there, and also that of his siblings. I've also found what looks like the burial of his father (William) and also the burial of one of his sisters.
So far I haven't found his parent marriage yet though, however they may well have married in a different nearby parish. I've not found the marriage in Waltham or Wye.
Unfortunately the site doesn't have the parish registers for Mersham on it yet which is a same as I think William's parents may have married there, and it is also where Mary Essex was from according to the Marriage Licence. Hopefully though I can find the Mersham PRs when I go to the SoG this week.
Many Thanks again for the help here.
Matt
