Re: A few answers about lost Duty's

I show Joseph Duty (son of Andrew Woodbury Duty and Martha Ankron)b. 26 May 1827 in Tyler County, West Virginia; d. 26 Jan. 1900 in Marietta, Ohio; m. 1st:Christina Martha Davis on 2 May 1844 in Tyler County, West Virginia.They had the following 8 children:Lenora Suzannah Duty b. 1846; Victoria Duty b. 1848; Andrew Duty b. 1850; Martha Duty b. 1 June 1853; Sylvanus Duty b. 1 June 1853; Landora Duty b. 22 Feb 1856; John Duty b. 24 Feb. 1862; Phoebe Ellen Duty b. 25 Oct. 1864.Since the records are showing same birth date for Martha and Sylvanus Duty, would I be correct to assume they were twins?Would like additional data on this.I also show Joseph Duty married 2nd: Sarah Katherine Boyce, but don't have any information about her. I would like to be able to gather additional information about this family, if at all possible.I hope this helps you and would love to hear from other Duty family members with additional Duty Family data.
