Thank you for your reply.
RE: "Bpt 22.6.1788 Moses son of Joseph & Ann
BTs has parents as Joseph & Alice" I am inclined to think Ann was an error in the records, but I am not certain.
There is a record of Joseph Pegg marrying Alice Doughty, 28 Apr 1772, at Wickmere with Wolterton, Norfolk, which may be them. Alice, age 66, wife of Joseph Pegg, was buried 14 May 1819 in Wood Dalling, Norfolk, Bishops Transcripts. Joseph Pegg, age 70, was buried 21 Feb 1820 in Wood Dalling, Norfolk, Bishops Transcripts.
My working assumption is that the baptisms you mentioned are their children, but I cannot be sure. I assume when the first Moses died, they named another son after him. I have seen that pattern in other families after a child died.
Their first recorded child seems to have been Elizabeth Pegg, baptism 28 Nov 1773, Baconsthorpe, Norfolk, with a possible burial 18 June 1774, Baconsthorpe.
Other possible children:
Elizabeth Pegg, baptism 27 Apr 1777, Wood Dalling, Norfolk with a possible burial 4 May 1778, Wood Dalling, Norfolk.
Elizabeth Pegg baptism 14 June 1778, Wood Dalling, Norfolk
Susan Pegg, baptism 9 Feb 1783, Wood Dalling, Norfolk
Alice Pegg, baptism 12 Dec 1784, Wood Dalling, Norfolk
Moses Pegg baptism 11 Feb 1787, Wood Dalling, Norfolk with a possible burial 25 Mar 1787, Wood Dalling, Norfolk
Moses Pegg baptism 29 June 1788, Wood Dalling, Norfolk
Phebe Pegg baptism 29 Oct 1791, Wood Dalling, Norfolk
A birth for Paul Pegg in 1792/Jan 1793 would have been possible if he was 66 when he was buried on 24 Jan 1859 in Stanfield, or in 1790/Jan 1791 if he was 68 when he died at Stanfield January 16th 1859.
