There's a marriage of William Holmes to Alice Allan in Bellshill in 1912.
Then there are lots of Holmes births and deaths with mother's maiden surname Allan - all in Bellshill unless otherwise stated
James, 1912
John Allan, 1913, d 1913
William, 1914 d 1914
Mary Ann, 1914 Glasgow Anderston d 1981, Glasgow
George Allan, 1915
William Allan, 1917 d 1983, Auchterderran
Alexander, died 1994, Auchterderran
Robert, died 1921, Bellshill
Mary, died 1923, Bellshill
Mary, 1925
Doreen, 1926, Old Monkland
Mary Rough, 1928 d 1982, Falkirk
Joseph Smith, 1928, Old Monkland d 1929, Old Monkland
Margaret Crossan, 1929 d 1929
Alice Allan, 1931, Auchterderran
Margaret Crossan, 1933, Auchterderran
Moira, 1933, Old Monkland
Robert, 1936, Auchterderran
not all of whom are the same family, obviously. The Old Monkland ones are almost certainly the family of Joseph Smith Holmes, who married Jeanie Gibson Allan there in 1920, and Mary b 1914 in Glasgow and Mary Rough b 1928 look unlikely.
