It does get a tad confusing.
In this news article in 1872 John Morgan of Euroa was described as a decrepit
old man and a very old resident in the district.
My maternal ggg grandfather, John Morgan of Euroa, would have been 70 years old and most probably "decrepit" as he died in 1873 and yes he was indeed a very old resident in the district, having arrived in Euroa in the 1840s.
So I am assuming this is he.
