Thanks Clackmannan Person for the additional information from the Field Centre. I've been back over some of my old ground but also established some material that helps me anyway

.
From the Old Parish Registers a Tobias Bachop married a Margaret Lapslay on the 8th February 1684 in the parish of Alloa. The only birth for a Tobias Bachop that I could find over a long period was one who was baptised in 1674. Surely he couldn't have married aged 10ish (could he?). Two years on from their marriage Tobias and Margaret had a son baptised whom they called John - 1st May 1686 .
This time Margaret was Lapslie. Incidentally Lapsley (etc) is at odds with the Margaret Lindsay mentioned in Crawfords 'Memorials of the Parish of Alloa' of 1874 which you referred to.
Birth years for 'my/our' Tobias suggest 1710 to 1714. In 1710 to 1714 Tobias, the mason, would have been married some 26 years when 'my/our' Tobias was baptised.
i considered in an earlier post that the parents of 'my/our' Tobias may have been a John Bauchop and Helen Henderson. I cannot find a marriage but there are six baptisms shown to them in the following years -
1696 Andrew, 1701 John, 1704 John (as 1701), Thomas 1706, Tobias 1710.
Other possible parents were Tobias and Jean Arthur. There is a marriage between a Tobias Baak and Jean Arthur in December 1701. Children?;-
1703 Catharine, 1706 Robert, 1711 Janet, 1712 Tobias
The third suggestion for Tobias's parents were John Bauchop and Anna Mortimer. Again I cannot find a marriage but children;-
1707 Margaret, 1711 Anne, 1713 Isabel, 1714 Tobias
I don't think I'm any closer to the mason of Alloa
One final thing I found of interest in the light of your comment that Tobias made about forsaking his native church. The last few words of his marriage record reads ' . . . . by . . . order from the Bishop of Edinburgh'.
