Did you look at those births for Elisha & Hanna in Barrington? Most predate the census, so it is he...
In 1770 census ...They have six children...3 boys & 3 girls (Being that they declare all children to be "American"... which seems rather odd after having forced out the original native people who would "not claim allegiance to the crown"? )
The births in Barrington for Elisha & Hannah ( was she surname Wing?) were:
Marcy/Mary Hopkings 24 March 1763 ( thought they were twins but this may have been a correction for spelling as well since the names are so close....you'd have to see actual images to clear this up)
Elisha Hopkins 22 June 1765
Seth Hopkins 15 April 1774
Edward Hopkings 27 June 1767
Isaac Hopkings 15 October 177I
Archd B Hopkins circa 1795
...adding correction: two of these boys were born before & two after that census
Wow, there are some trees that have this order all jumbled
The births in Barrington for Samuel Elisha Sr's brother & Rebecca Pennell were:
Rebecca Hopkins 25 October 1782
Hannah Hopkins 28 April 1785
John Hopkins 23 July 1787
There is also a Larina Hopkins b. 30 January 1868 in Jeddore, Halifax, NS mother: Elizabeth Mitchell
In case that is also your fellow married previously ( There is a tree with a Samuel & several children with an Elizabeth Mitchell but the dates are 100 years later, unless someone has the dates wrong...)
Hmmm see there is a duplicate for this birth under Lavena Hopkins b. 30 January 1868, so although probably not yours it indicates, spellings were a cause for duplicate transcriptions so Mary/Marcy wrere likely also the same person
Some later generations in newspapers
