Hi Emjay,
On another site I had a connection which outlined Matthew's family. He was a goldminer when he emigrated to Oz. Himself and his wife Honora (b 1828) had 8 known children: James (1850), Mary (1854 - 15 Jul 1933), Ellen (1856), Thomas (1856 - 1856), Margaret (1858), William (1863) and Letitia (1868 - 15 Aug 1888). James was the only child born in Wicklow, the rest were all born in Bendigo, Victoria, Australia. As far as I can determine John's parents were John Pepper/Peppard (b.1800 Rathdrum, Wicklow - d. abt 1889 Dublin) and Elizabeth Sharpe (b. 02 Dec 1807 Knocklishen, Rathvilly, Co Carlow - d. Bet. Apr - Jun 1880 Dublin), they married in Rathdrum, Co Wicklow on 12 May 1822. Their other children were:
John (1838 Garrettstown, Rahill, Rathvilly, Co Carlow- 21 Nov 1926 31.1 Old Kilmainham, Usher's Quay, Dublin (my GGgrandfather)
Joseph (b. abt 1840 Baltinglass, Co Wicklow)
George (b. abt 1840 Baltinglass, Co Wicklow)
Jane ((b. abt 1855 Baltinglass, Co Wicklow - d. after 1876)
Hope this is of assist to you
