Aaron Wheeler was born in Glastonbury, Somerset, England in 1777, and came to Erin Township in 1824, having previously visited Newfoundland, but returned to England.  He was accompanied by his wife and two daughters.  They settled on lot 25, con. 8, the site of the Hillsburgh Community Hall, where he built his log house.  The first baking his wife did, was after they arrived in Erin Twp.  They built a fire on a flat stone, and after brushing it off, cooked scones on the hot stones.  One wall of her log cabin was a huge fireplace, over which all the cooking was done for many years.  Aaron Wheeler married Betsy Lucans in England and they had two daughters, Ann and Mary.

The first Grist Mill was built by Aaron Wheeler on the west branch of the Credit River, soon after his arrival in 1824.   His dam had a fall of six feet.  The mill was driven by a breast-wheel ten feet in diameter.  The log building was about 18 ft. x 20 ft in size, one storey high, with a few loose boards laid across the beams for flooring.  One of the gables was left open, and a few logs were laid from it to the bank, upon which to walk while carrying the bags of grist.  One had to be carful to keep to the centre of the building while carrying the bags, or they could catch on the roof and get torn.    This description was written by John Dobbin in "Memoirs" her wrote in 1866, while he was Reeve of West Garafraxa Twp.    The Dobbins came to Garafraxa in July 1826, and made one trip to Hillsburgh with grist.  It was a very slow operating mill, and soon became inadequate to meet the needs of the increasing population, so, it was later sold, and became a woollen mill. 

Aaron Wheeler's second wife was Leah Cox, and their family included: Isabella, Mrs. Robert Smart; Sarah, Mrs. Angus McArthur and Robert Wheeler.

His tomb stone at Conningsby Cemetery reads as follows:  In memory of Aaron Wheeler, died Nov. 17, 1860 age 84 years.  Native of Somersetshire, England.
