Hi Keith
When looking at the LDS IGI, its a good idea to check the film details. Looking at your 2 records
1. baptism 28 Aug 1843 is film 0097351 - Bishop's transcripts, 1689-1870 Church of England. Parish Church of Beetham
2. baptism 22 Oct 1843 is film 1068856 - Bishop's transcripts of All Saints Church (Speke), Holy Trinity Church and St. Mary's Church (Wavertree), 1876-1880. Church of England. All Saints Church (Speke, Lancashire) OR Items 3-5 Bishop's transcripts, 1606-1893 Church of England. Parish Church of Halsall (Lancashire)
These are both BTs so yet another level of transcription exists. I have found in my research that sometimes the church scribe, rather than the recent transcribers have made the error. The dates for the second film indicate, as mentioned before, that it could not be the Wavertree - so perhaps it is in the Halsall record.
Genuki gives the history of the Wavetree church
http://www.genuki.org.uk/big/eng/LAN/Wavertree/StMary.shtmlIt does mention In 1837 a small church was built in Sandown Lane, Wavertree Liverpool but this was at first unsuccessful. Premises were rented in Martin's Lane for some time in the 1840s until another start was made in Sandown Lane.
I have found the IGI to be mostly very accurate, but usually (when time permits) order and check their film. This would seem a good idea for these records.
