Too many Georges

[Lindsay]

George Senior's marriage licence of 22 Oct 1753 (on FMP) said that he was of Silkstone, Yorkshire and age 22 - so born 1731.

That fits perfectly with this baptism at Silkstone on 14 April 1731, George son of George Senior of Hoylandswaine:

Other children apparently with the same father are:
Stillborn child Buried 12 Aug 1723
Martha bap 15 Aug 1724 Buried 20 Nov 1730
Ann bap 15 Aug 1724. Buried 10 Nov 1724
Elizabeth bap 15 Sept 1727 Buried 12 Nov 1730
Rebekah bap 14 Mar 1730/31
George bap 14 April 1731
Martha 29 Apr 1733
George bap 14 Sept 1735

The problem I have is with Rebekah, bap. a month before George, and the 2nd George bap. in 1735.

Vicar's mistakes? Any opinions welcome.
