Thanks JM I did see that Henry Lawson was born in Grenfell but his parents married in Mudgee. There are still a few different deaths of men named Charles Lawson and another likely one died in 1921 in Broken Hill. It gets so complicated with both the Lawson's and the Trenwith's using different given names as well as their surnames being varied. For example Ede's Dad who was baptized as Percival William Thomas Lawson, went by the name of Tom Gibson in his teen years and later on. His mother Maude May Lawson, nee Trenwith had children by a father unknown and then by William John Gibson in 1907. She married William John Gibson in 1912 and he died on the 14th July, 1912, so probably a marriage to a dying man she had lived with for years.
