Thanks Shona and Kate. Peter Grieve married Jane Galloway in 1824 and this is a fact as some of our relatives had Galloway in their name.

I omitted to say that Peter Grieve in the 1841 census shows

1841 Census

Peter Grive
aged 35, estimated birth year abt 1806
born Paisley Renfrew
Paisley
Address No 10 Smiths St
Occupation Cotton H L W
Parish Number 559
Ed 20A


Alexander Grive abt 1825 Renfrew Paisley Low Renfrew
Janet Grive abt 1839 Renfrew Paisley Low Renfrew
Jean Grive abt 1831 Renfrew Paisley Low Renfrew
John Grive abt 1826 Renfrew Paisley Low Renfrew
Mary Grive abt 1807 Renfrew Paisley Low Renfrew
Mary Grive abt 1829 Renfrew Paisley Low Renfrew
Peter Grive abt 1806 Renfrew Paisley Low Renfrew
Peter Grive abt 1836 Renfrew Paisley Low Renfrew

A mixture of ages here, but shows Peter b 1806 a sibling Mary born 1807, and some adults Peter (1836) Mary (1829) John (1826) Janet 1839) Jean (1831)

Referring to the name patterns, Peter & Jane had two children named Jane & John - so do I discount the other names suggested? I'm a little bit confused now.

I do appreciate your help. (and thanks Babs)

Notice how the surname changes from Greeve Greive Grieve Grive.
