There was only one congregation of 40 Witnesses in Monterrey, but by the time she was transferred to Mexico City in 1950, there were four congregations.
Tajā laikā vienīgajā Monterrejas draudzē bija 40 liecinieki, bet 1950. gadā, kad Estere pārcēlās uz Mehiko, Monterrejā bija izveidotas jau četras draudzes.
