Okay - i've had a closer look and now realised i may have given you some incorrect information (sorry about that) - see below.
Looking at other Lairs in the Script Book, its apparent that (as well as being something of a 'dogs-dinner') other burial entries are indicated as "
adult" or "
child" along with the date of burial. The dates shown in David McIntyres Script Book entry for Lair 2-X-157 don't indicate adult or child burials (apart from his wife Helen).
Also, if you look carefully at the Script Book entry, you can see that the cost of David McIntyres Lair was "
£3.3s.0d" or "
1 @ 63/-" (three pounds & three shillings is the same as 63 shillings). You can just see the lair below belonging to Mrs Margaret Pollock was also £3.3s.0d. In fact, at this time, they were all £3.3s.0d for this type of Lair.
The first column is a 'debit' account. The second column is a 'credit' account. So, in other words, David McIntyre did not settle the bill for the Lair in full until 4-Jan-1919 with your Certificate being issued on 16-Jan-1919. He paid in instalments of £1.11s.6d + 10s + 10s + 5s + 5s + 1s.6d = £3.3s.0d on the dates indicated (of course, nowadays, he'd be charged interest for taking 5years to pay the bill!)
So it looks like nobody else is buried in Lair 2-X-157, just his wife Helen at a depth of 8 feet (so still plenty of room for subsequent occupants).
Apologies for misleading you initially.
I've checked on FindAGrave.com - there was no entry for Helen, so I have created one for her - see
