Hi Ruth
I too had seen the 1891 Cambridge wedding - they had four subsequent children in the 1890's which I was hoping may have married in Alconbury, hence my question, but no such luck. Where does it say though that they were both from Cambridge? I couldn't see it - the other thing about all those IGI entries is that they are member submissions, so you should have the salt pot at your side ready to take a large pinch (having said that they do look reasonably authentic, apart from one)
The marriages - Sam appears to have remarried pretty rapidly after the death of Elizabeth in 1825, and I assume it was his second wife who died aged 76 in 1839.
I suspect that Ann and William, plus Joseph who died in 1829, could have been siblings of your Mary. It is probably significant that Elizabeth in 1825 was the only Palmer buried in AW in the period 1760-1825, so it doesn't seem as though Samuel was from the village, even though he may have married outside the county. I wouldn't rule out that Cambridge marriage!!! (think about the one you found for me on Saturday - Caxton, Cambs and Somersham Hunts married in Huntingdon)
Check out the Cambs FHS website
http://www.cfhs.org.uk/Search.html- burial and baptism indexes - one of Samuel & Elizabeth's daughters was buried in 1802, but this is the only mention of the family - no more baptisms, but neither parent was buried (unless of course one or other of them died just prior to 1801 when the index starts). It will be interesting to see what the AW parish register says about the various children.
I've just browsed (you're not going to hear the end of that!) Alconbury, as opposed to AW, 1841 as I found William and Ann there in 1861, and found them, or what seems to be them, enumerated as Parmer. I'll continue browsing once I've finished the school run and bought a baguette, and post the result later.
regards
David
