John Garrett, IV - Need Help

I'm trying to connect some dots from my personal tree onto Geni and want to make sure I don't connect them wrong.

This site has the various John Garretts numbered different. This one is listed as John V, but he's the one who is a son of John Garrett IV and Frances Buckner:

However, it doesn't show his wife as Frances Scott. It has her as Frances Dudley:

Here is what it has for his parents:

GENERATION FOUR

JOHN GARRETT IV (c1675 VA-) m. FRANCES BUCKNER, d/o JOHN BUCKNER (c1631-1701) and DEBORAH FERRERS

John Garrett IV was prominent in Essex Co., Virginia. Gabriel Long, son of Richard Long was the great grandson of John Garrett IV and Frances Buckner, had license for a tavern at Buckner’s Hill. John Buckner married Deborah Ferrers in London on July 10, 1661 and emmigrated with his brother Philip Buckner to the Virginia Colony by July 1665. In 1667 he bought his first land in Gloucester Co., VA. About 1680 John brought the 1st printing press from England to the VA Colony. The Buckner land was handed down the family until it was sold by another John Buckner in 1782 to William John and Lucy Taliaferro, who changed the Buckner homestead to the name "Marlfield". John Buckner and Deborah Ferrers had at least 5 children: William, Richard, Thomas, John and Frances.

Then it goes into the part for John Garrett V, son of the above couple:

GENERATION FIVE

Frances Garrett (c1732-AFT 1784) married George Longmire 8. Lucy Garrett (c1734-1784/1798) married Richard Lowry.

The part that is most relevant for me, aside from making sure the correct name of this John's wife or whether he was married more than once, is his son James, who is my direct ancestor:

James Garrett - his daughter Dolly Garrett (1765-1810), daughter of James Garrett, m. Benjamin McCary (1763-1804) m. Abt. 1785 in Edgefield, SC, Dolly Garrett married age 19 and Benjamin McCary married at age 21, in 1784. Children: 1. Tandy 1785 m. Elizabeth Brown, age 5 on 1790 census, age 15 on the 1800 census 2. Roland 1787 age 3 on the 1790 census, age 13 on the 1800 census 3. Benjamin 1789 infant on the 1790 census, age 11 on the 1800 census 4. Nancy 1791 age 9 on the 1800 census 5. Susannah 1793 age 7 on the 1800 census Sources: 1. The 1870 Shelby Co., SC census shows Roland McCary age 81 (b. 1789), 2. The 1790 Edgefield, SC census shows Benjamin McCary and wife with 3 sons under 16 (1-3-1) sons ages 2; b. 1789, 4; b. 1787; and 6 b. 1785. 3. The 1800 Edgefield Co., SC census shows Benjamin McCary and his wife and possibly her mother with 3 males 10-15 [Tandy 15, Roland 13 and Benjamin 11] and 2 females 0-9 [Susannah 9, b. 1793 and Nancy 7, b. 1791] (03010 / 20011). 4. Dolly's 2/4/1810 will names son Tandy regarding the purchase of personal property and her minor children Roland, Benjamin, Nancy and Susannah.

The marriage of this James' daughter Dolly to Benjamin McCary is my line, from their son Tandy. I have 'up to' Tandy on Geni already but all the records I've seen show a Chloe Davenport as his wife, which has nothing to do with trying to make sure I get his mother's Garrett line correct, but it complicates things when only one wife of someone who married more than once is listed.

Anyway, Dolly Garrett and Benjamin McCary are my 5th great-grandparents, their son Tandy is my 4th ggf. I just need confirmation about the multiple marriages for this John Garrett IV / V and Tandy McCary because:

1) Geni only shows the Scott marriage for this John and the link I found with the Garrett genealogy only shows Frances Dudley as his wife

2) The Garrett genealogy link only shows Elizabeth Brown as Tandy McCary's wife and I'd only ever heard of my 3rd ggm Chloe Davenport as his wife. It's also confusing that it mentions this Elizabeth Brown as his wife in conjunction with his appearing on a census when he was 5 years old and it doesn't mention spouses for his other young siblings on the same census. So, I don't even know how reliable that marriage comment is. The brother Roland mentioned right after Tandy on the census matches what is in my tree.

Tandy K. McCary
