I'm going to update an old posting.
Ephraim Garwood's(1825-1882) first wife was Elizabeth Ann Hewitt. They were married in 1850 and she evidently died, before 1856, when he married Ann Woolston (1837-1904).
Ann's is indeed the sister of Isaac Morgan Woolston (1826-1903). It is information about their parents Charles and Margaret Woolston I am seaking to discover.
Ephraim and Ann had at least two children - Ellwood(1858-1915) and Viola - born about 1860.
Ellwood Garwood married Lillie Samson and had two sons -- Ellwood Samson Garwood and Hobart Allen Garwood.
In 1870 Ephraim and Ann Garwood had a Sarah Woolston (born about 1851) also living with them. I would also be interested in discovering information about Sarah.
In reflecting upon the names of the Garwood children, I do know their is a connection between the Woolston's and William Wilson Allen (1837-1913). He served in the civil war with Isaac Morgan Woolson and married his daughter, Anna Maria Woolston (1848-1917). Whether Hobart Allen Garwood's name is associated with this is unknown.
It is also possible that some of the Garwood's are unidentified in a Woolston family reunion picture I have from 1902.
