I have been looking for information on George and Esther Allen, who show up in the 1860 census in Orleans, CT, Brownington, VT but do not show up in any other US census after that. A marriage certificate for Edgar Allen b. 1863 indicates that he was born in Maidstone, VT.
I cannot find this family in Maidstone in 1870 or in any other US census after 1860. The 1860 census indicates that George Allen was born in 1830 in England and his wife Esther was born in 1833 in Canada, but the marriage certificate says New Hampshire. Their children are as follows:

Emily b.1851
Martha b. 1855
George E. b. 1853
Edgar L. b. 1863 (my g.grandfather who married Lizzie Beattie in Massachusetts)
Flora(?), Floria(?) b.1859 can't read name too well on this census.

The 1860 census also indicates that all the children were born in VT and that George owned property and was a farmer. If anyone has any information that would help me to figure out what happened to the family or vital statistic information, I would appreciate it. If the information on the marriage certificate is most likely wrong, that information would be helpful to know.

Thanks
