One of the baptisms of George Crossman and William Crossman in 1806 which are in the IGI and in the Tavistock PRs is likely to have been attributed by clerical error to the wrong parents, George Crossman, carpenter, and Elizabeth Ford, and the other baptism likely should have been attributed to George Crossman, labourer, and Elizabeth Jago. This is because one baptism is in April 1806 and the next in June 1806.
The death certificate of George Crossman, the labourer, on 2 Jun 1846 at Lower Back St Tavistock shows the informant is George Crossman. George Crossman, the carpenter, died on 22 Jun 1840 at Two Bridges Tavistock and the informant was Philip Crossman.
George Crossman married Mary Oats on 20 Apr 1829 at Ilfracombe DEV per IGI Batch M051211. The Devon OPC for Ilfracombe says that the Ilfracombe PRs contain entry 343 on 20 April 1829 (Banns) George Crossman ( Bach) soj in this parish x his mark
Mary Oats (spin) of this parish Witts (Wm Richards) &(C Greenslade)

1239 Mary b 6 July 1829
1343 Phillip Oats b 26Dec 1830

Hemmum has the certificate of the marriage of George Crossman, brickmaker, to Mary Jane Carter in 1848 at the Brook Street Independent Chapel in Tavistock which shows his father is George Crossman, labourer.
Regarding the baptism of William Crossman in 1806, there is an entry in the Stoke Damerel parish register records for the marriage of William Crossman, Carpenter, and Elizabeth Glass, Spinster, by Banns, on 10th November 1829. The witnesses were Elizabeth Harris and another person whose surname appears to be 'Nettle'. Unfortunately there is no indication of the name of William's father. It appears that William and Elizabeth had a son, George William, baptised on 13 Mar 1832 at Plymouth St Andrew. It would be good to confirm that this William Crossman is the son George Crossman, carpenter, and Elizabeth Ford, as it would support the possibility that George Crossman baptised in 1806 is the son of George Crossman, labourer, and Elizabeth Jago.
