2 James McMahon's. Could they be the same person?

[McMahonCore]

Hi all,

Interesting one here. I am trying to find a connection between my own family line and an exact DNA match currently living in Australia. Given the exact match there is a high probability we have a common ancestor in the last 200 years. This is the information I have gathered on both sides in an attempt to make the connection. After much thought I believe the 2 James McMahon's below may be the same person.

My Family Line:

James McMahon: B. Ireland 1841, D. Ireland 1923. Travelled to Australia (possibly Orange NSW) in the 1860's as a gold prospector. Ended up in Sydney around 1890. Invested all his earnings in he National Bank of Commerce in Sydney but lost the lot in the bank collapse of 1893. He had returned home to Ireland by 1901. I have no record of him having children.

Australian Family Line:

James McMahon B. ~1833???. Son David McMahon B. 1867 Port Adelaide SA. David married Emma Lilian Daniel (B. 1877 D. 1940) on 12 December 1899 in Adelaide. Their sons Marshall B. 1900 and Maurice B. 1902 were born in Exeter, Port Adelaide.

I suppose my question would be, is there any information out there on the James McMahon on the Australian side that might help me. I'm sorry that I am short on information but any suggestions would would be appreciated.

Thanks,
Noel McMahon.

I am a little confused as to why you would think a James McMahon in Adelaide South Australia could be the same person as a James McMahon near Sydney NSW.

Long, long way apart

I cannot see a birth for a David McMahon in 1867 in SA either

Thanks Neil. Sorry, should have mentioned that James McMahon in the Australian line originally came from around the Sydney area. Without info on David's birth I can't see us finding anything new.

In reality it's not the best idea to be trying to get people to fit DNA results. Should be the other way around. I don't have a lot of information from the Ausrtalin contact so it's a difficult one.

Hi there

McMAHON is quite a popular surname in NSW and of course James is among the most popular of male first names ......

As you have details about a South Australian family  have you contacted the person who provided that DNA and that info ?  I am presuming they provided it to the DNA clinic ....  I am presuming they provided both the sample and info in order  to get direct contact with others and that the clinic would notify them of your matching profile. 
 
There may be many Different James McMahon chaps in NSW and in Sth Australia in the late 1800s and most descendants of those different families are yet to even consider any family history much less DNA as a source for fh buffs   

Have you validated your own James details for his time in NSW or are you looking for help with him?

Cheers JM

NSW BDM seems to offline at the moment so cannot do any checking there for any possible connection

Very long shot 
But it gives a Sydney-Adelaide-Ireland connection

NSW BDM is working for me Neil but there are 8 pages of James McMahon's

I rarely place much reliance on submitted trees, but may I note that there is a submitted tree which has David as born in IRELAND.

The tree also has uploaded the 1899 marriage cert for David McMAHON. 
12 December 1899 married in the District of Adelaide. 
David McMAHON  32,  Bachelor, (Trade or Calling) Engineer, (Residence at time of Marriage) Adelaide, (Name and Surname of Father)  James McMahon,
(Place in which celebrated) : Rev J Thome's House, Franklin St, Adelaide
 Emma Lilian DANIEL 22, Spinster, Adelaide, (Father:) James Daniel.
Witnesses  John (cannot clearly decipher surname, could be Minapav) Bootmaker, Franklin St, Adelaide and Elizabeth Jane LAYTON, Charwoman of O'Halloran St, Adelaide.
Bride, Groom and Witnesses all signed.   So too John Thome, Officiating Minister.

Cheers,  JM

Re that submitted tree

The following seems to rule out the Irish death that the OP mentions about his own James McMahon.

The submitted tree has their James as
1833 (abt) Born Ireland
1855 Arrive Australia 10 May (NO ship, NO port  )
1863 Marriage in Adelaide,  to unknown
1895 death Southwark South Australia
two offspring (eldest as John McMahon, no further details, and then David as per my earlier post)

PS, the submitted tree has the Rev on that 1899 marriage as Rev Thorpe.   I have double checked, cannot see the letter "p" but it may read Thorne rather than Thome.  Recorded twice on the mc.  Neither could be read as Thorpe. 

Cheers,  JM

South Australian papers 

http://trove.nla.gov.au/ndp/del/article/48254928 South Australian Register 10 Nov 1891

NSW papers also had earlier notices     (I searched using street address from Ros' great find)

http://trove.nla.gov.au/ndp/del/article/13871845  SMH 4 Nov 1891.  Mentions the Rev John McMahon connection, in one of the several announcements.   Another announcement on that page gives a daughter as Miss Bride McMahon. 

ADD
I have just tried NSW BDM online index.  There's over 50 lasses with given name of "Bride" marrying between 1891 and current closing date of the online listings.     and none with McMahon or variations....
