Hi aussiegalx,
I think the first thing you need is to get that entire 1828 marriage entry and see if Philippa's marital status is listed.
I have looked and looked for this also and have not found another option for Philippa. The one thing I am not particularly keen on re Philadelphia Skidgemore is that she was baptised in 1791. You Philippa is very consistant with a birth in 1796 as gained from 1841-1861 census.
The only inconsistency I see is... I presume Philippa died in 1864 listing at burial 9 Dec 1864 aged 75 years (way out from aged 65 in 1861 and 75 in 1864) of Wrestling Downs (Coroners Inquest)
http://freepages.genealogy.rootsweb.com/~staustell/Data/Bur/SA/SA1860-64O-Z.htmNow if your Philippa is the same person as Philadelphia/William we note they had at least 3 children in St Stephen in Brannel 1817-1821.
Amelia 4 Jan 1817
Eliza 25 Dec 1819
Angelet 12 Jun 1821
There is the possible burial for William 13 Oct 1824 St Stephens in Brannel aged 37 years.
Now from there we have the baptism of Fanny 13 Feb 1825 St Stephens in Brannel parents listed William and Philippa . Now if this is the same couple father William is dead. I would think the actual entry should say so.
(Childrens names and ages are roughly similar enough to
maybe be the children from 1841 census and I do not see other possibilities for Philadelphia and these children in 1841 census nor burials before 1837)
Now these records are all St Stephen in Brannel, so you have several options to gain the entire entries for these events. I know the OPC has been previously mentioned.
http://freepages.genealogy.rootsweb.com/%7Eboneplace/stsib.htmlDid you contact her? If she is unable to help, the Cornwall Records Office will be able to supply copies of these records for you for a small fee. You could try emailing them and giving the dates and asking for the full entries. They are very accommodating, where you already have the parish and date. Also you could hire the St Stephen films from your local LDS library, not expensive.
These baptisms are after the forms appear so a more information is available from the complete entries. I would be interested in Residence and Occupation of William re the baptisms of the 3 children listed to William and Philadelphia and compare it with the baptism listed to William and Fanny in 1825. Also is there mention of William being deceased at that 1825 baptism.
Most importantly of all - the marriage to James Snell - What is Philippa's marital status?
All the best............Kris
