From looking at the various records, and your previous posts re. this family, it would seem to me that Ellen Hamilton bc.1846 Deptford (who married William Dyer) is the daughter of Charles Hamilton, Mariner (and not John as stated at marriage). There was only one Ellen Hamilton born in Deptford at this time and she's the daughter of Charles and Charlotte. This Ellen 'disappears' when your Ellen marries William Dyer.
So, you end up with a Charles Hamilton, Mariner, bc.1791 Kent (per 1841 census) married to Charlotte Mary Edmeades in Frindsbury, Kent 1831. Has this marriage been checked? Was Charles definitely a bachelor? He would have been 40 at time of the marriage.
FACTS
1841 Charles with Charlotte and son Arthur 7 in Deptford (Arthur Adgate born 25/2/1834, bp.13/9/1840 St. Paul Deptford).
1851 - Charlotte 45 with dau. Ellen 5 in Greenwich.
I note a Charlotte Hamilton d.Mar.1860 Greenwich and wonder if this is her? This would explain why:
1861 Ellen Hamilton 32 husband at sea
William Hamilton 14
Ellen Hamilton 15 Sister (which I believe should be sister in law)
Working back from 1861 census it has been established that William Hamilton, Mariner (of full age), son of Charles Hamilton, Mariner, married Ellen Aubery 1/7/1850 St. Nicholas, Deptford so son William bc.1846/7 Deptford was actually born prior to their marriage.
By 1871 Ellen Hamilton (younger) had married William Dyer. The older Ellen is still with son William 24. Cannot find any trace of either after 1871.
So, the various records show Charles Hamilton and Charlotte Mary had Arthur (b.1834 but not baptised until 1840), a Charles George b.1836, bp.1837. As they didn't baptise Arthur at the same time (waited until 1840) one wonders whether Charles George was sickly hence swift baptism. I note a Charles George Hamilton died Dec.qtr.1838 Camberwell which could possibly be him. Certainly not around in 1841 when he'd only have been 4.
This then leaves the son William about whom next to nothing is known. No birthdate or birthplace actually known, no obvious trace of him in 1841. So, was he indeed a son of both Charles and Charlotte Mary or had Charles been married before and William a child of that union? If he'd been born ca.1831 surely being only 10 years old he'd have been with his parents and Arthur in 1841. Hence my query as to whether it is know that Charles, then 40, was still a bachelor when he married Charlotte Mary 1831 or could he have been a widower.
Both Charles and William, both mariners, seem to disappear so does one conclude they were lost at sea? Also, there seems no trace of Arthur after 1841 either? Did he become a mariner like father and brother?
