Facts and Events
John Dugger was born ca 1824/25 (per age on 1850 census) somewhere in TN (also per 1850 census).
Who were John's parents? Since he married in Roane Co., TN in 1844 it seems likely his parents would be listed there on the 1840 census. There were six Dugger households in Roane on that census. John would have been about 15 years old in 1840, so he should be in either the 10-14 age group (born ca 1815/1820) or the 15-19 group (born ca 1810/1815). Four of those listed had no apparent sons that age.
Alexander Dugger had one apparent son in each of those age groups. Another Alexander Dugger had one son 10-14. These two seem the only choices for John's household, but more evidence is needed before linking John to either of them.
John Dugger married Mary Taylor on 25 Jan 1844 in Roane Co., TN.
They moved to Perry Co., AR ca 1849 and were listed there on the 1850 census, the only Duggers in that county at the time.
They were listed on the 1860 census in Perry Co., AR.
