If this is the right chap (and it certainly looks a strong chance) he would have been born c. 1865, and therefore about 32 when he played that game for Carlton in 1897. So if he did move to WA a few years later (Steve Williamson thinks he was living at Coburg until 1900?) he may not have had a lot of football playing left in him by that stage.Addition to the above
In the Obit it states he served in the 44th AIF the AIF page says he enlisted in Perth and gives all the correct information
Maybe look to Perth for any football/bio info
An Ahearn played in Kalgoorlie/Boulder in 1901 http://nla.gov.au/nla.news-article89027165
That seems to be the only football reference to an Ahearn/Ahern in the west.
It's pretty likely that the Ahern who played for Preston in 1893 is the same one who played for them in 1895, so it seems a bit odd S. Williamson has only spoken about him being at the club in 1893.
