Oh dear, now what are they doing? This morning I had two 'order fulfilled' emails for wills that I downloaded ages ago and have since expired! I have only had a few of my outstanding orders so far, so that was quite a disappointment.

'Normally' - meaning before the mad panic to order over the last couple of weeks - the ones that were not ready almost straight away were taking about 5 to 10 days. However, if you had ordered several wills there seems to have been no obvious order in which they were produced.
Thinking logically, a few days without new orders from the website ought to have allowed them to catch up with some of the backlog. Unfortunately, I know of at least one person who ordered 'several hundred' wills last week,  so the backlog could be quite large.

I would certainly expect them to have been snowed under for the last couple of weeks! I have just had one this morning which was ordered on the fifth of November. That is clearly slower than 'normal' but better than it could have been. On the other hand I have one outstanding from the previous order on 28th October which may have got overlooked, or they may just be clearing straightforward ones first. 

When you say that the civil registration marriage index says they were married in St George Southwark, bear in mind that it is a Registration District not an individual place, and it is highly unlikely to have had only one church in it. Indeed you may well be looking for a catholic church since one or both of them could be Irish. I did not see the marriage on Findmypast and you have looked on Ancestry so unless someone can find it on Familysearch then you are probably better in the long run getting a copy certificate from https://www.gro.gov.uk/gro/content/certificates/login.asp
Afterthought - one-name.org/marriage-locator, which is still incomplete, says 'Sorry, we cannot locate the church for this marriage. The entry is located between entries for Southwark St Stephen and Southwark St George the Martyr RO, both in RD St George Southwark.' so a catholic or other non-conformist church seems likely.

Yes, I like the look of that one mckha. So he had lost two wives and the latest child in fairly quick succession - no wonder he decided to make a fresh start abroad. He probably intended to send for the children once he had got sufficiently established but it took some time.
Edit -Thinking about it a bit more that leaves an even narrower window for travel out, and sheds doubt on the electoral roll in reply 3.
Valcharlie - I don't know why my note says 'Australia', it was written a long time ago, but I understand it was not uncommon to start in Australia and then move on to New Zealand
