Thanks for your help. Everything you say agrees with what I had previously. That Clara was born before 1892 and Marguerite before 1900. There was also a William born before 1892 - not sure what happened in that year. Now thinking William born 1886/7 as first child after their marriage on Jan 23, 1886 in Vergennes. Addie was born Port Henry, New York about 1868. Does 1900 have her date of birth? I have that Samuel was born 1866, not 1886. Probably typo as you have his age as 14 in 1880.
Thanks again for your help
