Hi Tim
William and Mary Mylrea are my gggrandparents. I have their children as William(bap.1851),John (bap.1852),Mary Anne (bap.1857).Margaret (b.1856),William (bap 1858,died 1862),Thomas Daniel (bapt.1863),Phillip Herbert (b.1863),William Fredrick,also called Wilfred (1865),Elizabeth Jane (b.1867) and Francis Emily (b.1870)
From family records: Elizabeth Jane married Robert Cormode in 1899-daughter Bessie Cormode Kaighin. Francis Emily married Joseph Kaighin in 1904.
Can you also verify that John Mylrea went to Australia and William Fredrick went to South Africa.
I also have information that the first 2 Williams died from diptheria.
