I found listings for some of these men in the Biographical Index of South Australians. What is strange is that in David's (m: Sarah Dicker) and John (m: Emma Dicker) it says he arrived in 1849 on the HARRY LORREQUER. Only Jeffrey's says he arrived on the RENZI. I couldn't find a listing for John senior (the father) or William.
BISA is known to have errors and omissions but it might be worth checking passenger lists to see if there is an error here.

(note- when there is a surname capitalised with no christian name, as in HALLAM and NOTTAGE, this is a married daughter. The surname is her married name)
I also found this John - who married another of the DICKER girls, Emma. Emma is a sister to Adelaide and Sarah. John appears to be a brother to David.

I couldn't find a listing for John Fitzpatrick.
Anyway, that's the BISA Listings. I'll check Digger BDM's for the facts.
I found two births registerd to John White and Mary Ann ANTHONY in SA.

Here is the marriage for Elizabeth White to John Fitzpatrick. The age is seven years off her birth cert though. I couldn't match another Elizabeth White-father John White to the right birth date. It says she was 20 here, she would have been 27 (maybe she lied? It happened - or maybe it's the wrong Elizabeth)

After finding these marriage records and finding approx birth dates, I realized that Edmund must have been born here. I rechecked the BDM disc and only found this one. Mothers name is listed as Huntley but it could have been a missspelling or misheard name or a bad translation from original records. I think this is your Edmund.

I hope I haven't confused things for you with the question is the differing vessels in BISA. It's a bit of a mystery! Anyway, I hope it helps.
