I now have a complete chart going back
six generations to my 3rd G-Grandparents.* That's pretty cool. Perhaps I shouldn't be asking for more. But the more you have, the more you want.

I am now completely stuck to find any more direct ancestors. Quite often I have a marriage but cannot find the parents of one party - or indeed either of them. Without parents' names on marriage records, or at least an unusual surname, it is hard to go any further back. And often these older records are inherited and have no citations: I have no reason to doubt them, but...
Here are two examples:
1/ Mary COLLINS, b. 21 Jul 1822, Stoke Damerel, Devon**. I think can take her mother Ann SHOBBROOK back one more generation to her parents Joseph and Mary***, but all I have for her father is 'James COLLINS, mariner, b. ABT 1795' (inherited info - no citation).
I have no firm birth year or birthplace. Without a census for 1801 how can I possibly hope to find James's parents?
2/ Elizabeth BELL, b. ABT 1783 Satley, Durham, m. William RAINE, 21 Mar 1807 Satley. She's in census 1851 (with Francis BENNOCH) at Blackheath Park, Lewisham and 1861 (ditto) at The Knoll, Lewisham Hill, London. ****
I've got several like that. So is there more I can do? Or should I just give up and be grateful?
All suggestions welcomed!

* I have the following:
Gen 6: 32/32 (100% - yay!)
Gen 7: 45/64
Gen 8: 49/128
Gen 9 39/256
** Mary appears in census 1841 in Coldridge, Crediton, Devon. She marries Langford FROST, Q2 1843, Liverpool 20 171, and appears in later censuses:
1861: Downderry, St Germans.
1871: 7 St Stephens Road, St Germans.
1881: Dunheved House, Saltash.
[1851 n/a: Mary was in Ireland - see the birth of her daughter Elizabeth]
We also have CRO Doc X1338/3/6, leases and abstract of title, property in High Street, Launceston:
"Conveyance, two houses, shops, offices, stables, yards, High Street, Launceston. 25 Mar 1873. Parties: 1) Langford Frost, esquire, of Saltash, late captain in 57th Regiment who married his present wife Mary in 1843; 2) John Nicolls..."
*** Ann Collins nee Shobbrook
Census 1841: shopkeeper, Coldridge, Crediton, Devon. Also present, Mary Shobbrook age 75.
Mary Shobbrook died 1850 in Crediton reg dist and there is a useful postem on the record at FreeBMD:
"Died 29 November 1850, Coldridge, age 82, Widow of Joseph Shobbrook, Blacksmith. Death reported by Ann Collins (Present at death, of Coldridge)"
**** I have a possible lead from
The Law Advertiser 1831:
"'Bell, Anthony, formerly of Broomshields afterwards of Consett, farmer, then of Friarside in Tanfield, also of Wickham and Swalwell, farmer, miller and shopkeeper, afterwards of Hetton stream-mill, carrying on business with William Raine under the firm of Bell and Raine, millers Hetton stream-mill, and late of Easington lane, near Hetton le Hole, all in Durham, grocer and flour dealer.'
Is that Elizabeth's father in partnership with her husband? Could be...
