THis is confusing. Older Sam Feast who hybridized roses and started Samuel Feast & Sons is dated 1795 or 6 to 1868 and we found his Balt Sun obit for Feb 1868. Older John Feast, per the other Balt Sun obit was 80 in Oct 1868, so born in 1788. The John Feast, born in England who married Sarah Uppercue, is younger as he was 50 in 1860 and 66 in 1870, so the Census is not exact, but he was born 1810 or 1804, but certainly not in the late 1700's.
Is the John Feast who married Sarah Uppercue the brother of Sam Feast who hybridized roses? Then the very old John Feast 1788 - 1868 is an uncle or even not related? (Do you know approx birth and death dates on John Feast who married Sarah Uppercue?)
From the 1870 Census, also, there are Sam Feast 45 who married Caroline (or Sarah Neely?) with Adde 6, Clara 4 and Sam Jr 2 who lived next door to John E Feast 40 who married MJ (probably Mary J Neely) with Maria 8 and William 8. Are they the children of rose hybridizer Samuel Feast, so they are part of the 100-year Baltimore florist business? Thank you for clarifying! Kathy
