John emigrated to Australia, and married his wife Martha Marten Traynot (1854-1916) in Maldon, Victoria 10 April 1873.
Their son Joseph Alexander Wood, known as Joe, (1878-1950) is the grandgather of john Wood, whom I have a DNA match with. The DNA must surely come from the Lancashire Woods (as other closer relatives are Australian).
John Wood has a 8cM DNA match to me (and other Mather connections) and it must be via this John Wood of Astley Bridge born Q1/1849, since John Wood emigrated to Australia and married there. The GRO record shows his mother as SINGLETON and there are WOOD+SINGLETON births from 1838 (and before) to 1843 in Halliwell, and then untill 1853 in Sharples.
