In September 1920, Judy says: "She's ninety-three be the clock, she is." (PoSB 57)

In December 1933, upon discussion that Uncle Tom was sweet on a lady, Pat exclaims, "Why, he's sixty!" (MP 31)

When Tillytuck arrives at Silver Bush in November 1934 he says, "Christian name, Josiah...age, fifty-five...in politics, Liberal...religion, fundamentalist...gentleman-at-large, symbolically speaking. And an Orangeman." (MP 20)

In the spring of 1935, Judy says, "Forty-one years this very May, Patsy dear, since I tuk up wid Silver Bush, hoping to put the summer in if Long Alec's mother was suited wid me...and here I do be still." (MP 54)

On the day Rachel is born, this is said of Judy's silk dress: "She had had it for fifteen years, having got it in honor of the bride young Long Alec was bringing to Silver Bush." (PoSB 29) On PoSB 93, we learn that the anniversary is in March.

In the fall of 1925, when Pat complains that Winnie has a steady beau, Judy points out that she is eighteen, and quite old enough. (PoSB 190)

Pat says that she was five when the Armistice is signed (PoSB 197). The Armistice was signed November 11, 1918. We know from another source that her birthday is in the fall, so for her to have actually been five, her fifth birthday must have been the one in the fall of 1918. Hence she was born in Fall 1913.

The day that Rae is born, this is said of Judy's silk dress: "The last time she had worn it was six years ago at Grandmother Gardiner's funeral." (PoSB 29)

Judy wonders how a child who has been the baby for almost seven years will handle a new child. Pat was born in late 1913, but if Rae were born in summer 1919 (and we know her birthday is in the summer), Pat wouldn't have been almost seven. She would be almost six. For her to be almost seven, it would have to be summer 1920, and her birthday just a few months away.

In the rush of preparations for Christmas 1934, Pat says that this would be the first real Christmas since becoming the virtual mistress of Silver Bush. The year before (1933), Frank had had bronchitis, and the one before that (1932), Hazel's family had had measles. So Pat became mistress sometime in 1932. (MP 30) We also know that Hilary left Silver Bush right around that time.

Judy mentions that it has been thirteen years since she "wint hunting in the parsley bed for a new baby." Since Rachel was born in autumn 1920, it would be late 1933, but it is also spring, so the new year has passed, making it 1934. (MP 5)

Note: all of the dates after this point are based on Mistress Pat beginning in 1934.
