Lucky you! - Especially being able to visit the Manx Museum to do your research locally.
The reason that I put all sources in my replies to you, and showed you step by step why I moved from one source to the next, was to show you how to go about searching from the known to the unknown. For example Ellen Jane's marriage cert recorded her father as deceased, so the next step was looking for a likely death - and so it progressed. Please look carefully at all these steps and check the original records for each one in the Manx Museum library. Also look at the parish register entries, and build up a picture of the families.
In particular you need to check the marriage of Thomas GOLDSMITH & Ellinor SKILLICORN on 10 Sept 1831 Bride to see whether she was underage and whether any other details were given such as a placename.
There is only so much people on the board can tell you, and after all those details I wrote for you yesterday I see this morning (morning here) that elsewhere on the board you have posted a new message asking about "Ellen Jane Goldsmith, Daughter of Thomas Goldsmith and Eleanor (possibly nee Sayle)". As I wrote before, it is unlikely that your Thomas's wife was Eleanor Sayle. Did you not read the messages about Ellinor Skillicorn?
Proving or disproving these suggestions can only be done by you, by checking and recording the entries yourself, step by step as I showed you, and by looking at the parish registers firstly for the dates I gave you, and then expanding the search to family members. Also checking all the families through census records, and looking at the wills to find connections - there were many family members given in some of the wills (see BL's wills index to find possible siblings). It is a slow process and can't be done by anyone else. Start by drawing a chart of the people I gave you yesterday, and then check each one in the original record - as well as checking for all the other people mentioned in the wills.
