McEnnulty /McNulty

I am looking for a John McEnnulty ( McNulty ) born 1827 Mayo who travelled to Tamania Australia.
Have no idea how or when he arrived and no history on him at all till he married a Mary Ann Oldfield 31st October 1859 in Longford Tasmania when he was 32 - she was 29
The spelling of the surnames where McNulty and Mcennulty on the births of his children with Mary.
He died in Longford 1872
Mary then remarried to a John Joseph McSoley

Comments

Mary Ann's marriage to john Joseph McSoley apparently didnt last as she died a McEnnulty. Both John and Mary Ann McEnnulty are buried in the Perth Cemetery.
Mary Ann did have two children with McSoley but I have been unable to find them.
It has been suggested to me they may have been put into care or adopted out.
I still have been unable to find John Joseph McEnnulty ( McAnulty ) coming into Australia.
Some have suggest he may have been a convict but again I can find no record on him.
He did live at Perth Tasmania as he turns up in the census there along with Mary.

1852 - John Joseph McEnnulty
Arrival: Transported To Van Dieman's Land For 7 Years. Served 3 Years And 4 Months, Given A Pardon.
Have just found this on another site - but unable to find the info to back it up.
