I see on the 1901 census that she lists her birth date as 3-Dec-1871.
There's a baptismal record at the PEI public archives site for an Ursule LeCLERC b. 2-Dec-1871, bapt. 8-Dec-1871.Mother was Adelaide ARSENAUX, father was Paul LeCLERC.
On the 1881 census of PEI, district 1, township 1, pg 48-49 there's this family: LeCLAIR, Paul age 36 Delaide age 39 Mary age 15 Celina age 13 illegible male age 11 Ursule age 9 Peter age 7 Joseph age 5 illegible male age 3 Judith age 8/12
They are living next door to: LeCLAIR, Andrew age 61 Ursule age 57 illegible male age 22 John age 19 Daline age 15
In the 1891 census Ursule LeCLAIR, age 19, is still at home with her parents.
