Just a little FYI Clifford Eugene Langille is NOT listed in the 1891 census with William H and Janet aka Jennie Langille. He is listed in the 1891 census with his birth parents, with his birth name being Eugene C Langill age 2.
Also there is a mistake in his birth certificate filed by his brother Robert Nelson Langille in June 1947 I believe it is, it says he was born in 1890 but in the 12 April 1891 census he is clearly listed as being 2 years old at the time of census. He would be turn 3 in November of that year. Robert listed his birth name as Clifford Eugene as he was refered to as Clifford by his family members not Eugene. Just as Clifford and Louise's eldet son was born Clifford Marshall (I have his birth certificate) but went by Marshall.
Needless to say Scott Teal's book is incorrect as to his placement of Clifford. Not only that but this book totally over looks Clifford's actual family. Yes I realize oversites happen and mean no malace towards Scott Teal.
