Yes, sadly not uncommon at the time.
What do you as family researchers think of the possible new info posted yesterday?
I think John Wylie and Jean/Janet Whitelaw parted ways after the birth of David Donaldson Wylie...
John Wylie showed in his father William's Poor Relief application in 1890. He is listed as widowed and with one son living in Glasgow.
However, on John Wylie's 1881 marriage to Jane Whitelaw he was showing as widowed. He had married a Helen Brown a few years earlier who died young not long after. One son from that marriage, called William and born 1878.
Young William is showing with his paternal grandparents in 1881, William and Agnes (Porteous/Porter).
John Wylie did marry again (bigamously I would suggest). He married Agnes Hewitt in Glasgow in 1890. Showing on the census for 1891 in Glasgow is John, Agnes, young william from John's first marriage and Amelia Wylie. She was born in 1882 and registered as Hewitt to mother Agnes.
John Wylie did not die until 1939 in Cambuslang.
I have just found this family tree for this Wylie family with numerous original certs from SP. You need a subs to view so not sure how accessible this will be to you
www.ancestry.co.uk/family-tree/person/tree/1880871/person/352177423548/factsOn this tree, there are some errors for John such as the later censuses with the wrong family but I would focus on the original certs that have been included across the family for direction.
