I am looking for the parents of my great great grandfather Alexander McLean who was born on Islay circa 1821. Alexander was married in Lanarkshire in 1846 and died in Renfrewshire in 1875. My stumbling block is that his death certificate doesn't have any information about his parents. In looking for possible Alexander McLean births on Islay circa 1821, I found in the 1841 census an Alexander, age 20, apparently single and living with a family of Gilchrists. The census record is as follows: Peter Gilchrist, 50, tailor; Mary Gilchrist, 50; Marion Gilchrist, 15; Anne Gilchrist, 11; Peter Gilchrist, 8; Alexander McLean, 20; Mary Gilchrist, 16. I wonder if there are any McLeans or Gilchrists out there who can shed any light on this Alexander McLean?
