Hi Kay , did a little research on Trimmings in Farnham , following births 1880-1905
Mar Qtr 1882 Derenda
Sep Qtr 1886 Herbert
Mar Qtr 1889 Andrew
Mar Qtr 1892 Alice
Mar Qtr 1895 Fred
Jun Qtr 1895 George
Jun Qtr 1896 Eva
Jun Qtr 1897 Minnie
Dec Qtr 1897 Edith
Mar Qtr 1899 Ivy
Jun Qtr 1900 Ethel
Mar Qtr 1901 Maud
Sep Qtr 1902 Gertrude

Derenda (Mar Qtr 1882) , daughter of John Earwaker Trimming , married Walter Withall in Hale , 1907 (on IGI).

1881 census Farnham
John Trimming b Binstead age 25
Mary Ann Trimming b Wales age 24
Thomas Trimming b Farbham age 3
John Trimming b Farnham age 1

John Earwaker Trimming and Mary Ann Carver m 5/5/1877 Hale , John's father Thomas.

1881 census Farnham
Thomas Trimming b Binstead age 53
Suzan Trimming b Sussex age 49
William Trimming son age 19
Derenda Trimming daug age 14
Edwin Trimming son age 9

The John above age 25 is also their son , and they had daughter Alice ch 11/12/1864 in Farnham .

The Eva born jun qtr 1896 is on IGI ch 26/3/1896 in Hale Suerrey to William and Eliza Jane , they married in Farnham , William is no doubt the one aged 19 on the 1881 census .

So , the most likely first name would be either Alice born 1892 , Eva born 1896, Minnie born 1897 or Edith born 1897. Ivy would have only been 15 in 1914 .

All the births 1880-1905 are likely to be to John, William and Edwin.

Hope this gives some ideas.

Cheers
David
