Mary East as mother of the Alsup men is extremely suspicious.
Mary East [E4d], daughter of Thomas East Sr of Henrico Co VA and Dorothy Thomas, was born around the 1680s, and in 1726 when Mavel’s father wrote his will, “Item I give unto Mary Alsope my daughter one-shilling.” Mary had married William Alsop by then. Over the years, there has been a controversy whether Mary was actually Mary Mavel East. But if this was true, then why did her father call her Mary when she was married to Mr Alsop, and Mavel when she was married to Mr Robinson? Actually, it is far more likely that there were two daughters, and Mary was the youngest since the first mention of her was when Mary’s father wrote his will in 1726, thus indicating that she was either not born until years after Mavel, or wasn’t an adult until years after her father started giving gifts to his elder children in 1690.

(If this is true it is doubtful she married William Alsup sr, as he was born abt 1660)
Also, If there was a second younger daughter named Mary East, then there should have been Robinson/Alsup cousins galore!
Nowhere do we find an Robinson/Alsup connection after abt 1726.
The first burning question is: If the Alsup's and the Robinson's were half-brothers,, Where is there a connection?
Mavel East [E4b], daughter of Thomas East Sr of Henrico Co VA and Dorothy Thomas, was born about 1669. She married John Robinson 10 June 1690 and her father gave her a gift (a marriage gift?): “1/5 of a tract taken up by me, Robert Woodson, Sr., John Woodson, William Porter and Robert Clarke, 106 acres on the south side of White Oak Swamp, now is possession of John Robinson who married said Mavell East." John Robinson sold the land in 1696 and in 1704 Marvel Robinson relinquished her dower right. John Robinson died in 1721; his will was proven in July 1721.
On 1 August 1704 “John Robinson of Henrico Co, planter, sold to Thomas East Jr of same,” 404 acres on the north side of James River for 500 pounds of tobacco plus £3/6. John’s wife Mavel relinquished her dower right. A 16 May 1737 sale of 106 acres by “Thomas East of Hanover Co, son and heir of Thomas East, Sr of Henrico Co, dec’d,” to Sackvil Brewer of Henrico Co for £10 was for land on the south side of White Oak Swamp. The land was granted to Thomas East dec’d, William Porter, John Woodson, and Robert Clark. The land was “formerly given by Thomas East dec’d to his daughter Mavel East for life, which term being expired, land reverts to said Thomas East as heir at law.” This Thomas of Hanover Co was Mavel’s brother, and the transfer by Thomas to Brewer shows that Mavel had recently died, and the land then reverted to her brother Thomas, whereby he sold it to Brewer. So Mavel’s death probably took place in early 1737.
Repeating from the first paragraph. If Mavel was a younger sister to Mary, and she died in 1737, she would have been relatively young, possibly aged 40.
(Again, I find this doubtful, as I believe Mavel and Mary East were the same person.)
I believe Mavel East, widow of John Robinson, married, 2nd, William Alsup, abt 1723, either in Henrico or Hanover Co, VA.
My direct ancestor, William Alsup was born abt 1660, and he died abt 1730, Hanover Co, VA. I find it hard to believe that William and Mavel had offspring.
